Change signal model to match POSIX (i.e. one set of signal handlers
for the process, not a separate set for each thread). By default, the
process now only has signal handlers installed for SIGVTALRM, SIGINFO
and SIGCHLD. The thread kernel signal handler is installed for other
signals on demand. This means that SIG_IGN and SIG_DFL processing is now
left to the kernel, not the thread kernel.
Change the signal dispatch to no longer use a signal thread, and
call the signal handler using the stack of the thread that has the
signal pending.
Change the atomic lock method to use test-and-set asm code with
a yield if blocked. This introduces separate locks for each type
of object instead of blocking signals to prevent a context
switch. It was this blocking of signals that caused the performance
degradation the people have noted.
Replace the threaded locking with spinlock calls for both threaded
and non-threaded programs. This makes malloc thread safe for linking
with libpthread and kernel threads.
Stubs are required in libc so that it can be used with libpthread
(and kernel threads), but weak symbols and non-weak symbols of the
same name built into libc_r result in unpredictable linking.
Tighten up management of memory and swap space during map allocation,
deallocation cycles. This should provide a measurable improvement
on swap and memory allocation on loaded systems. It is unlikely a
complete solution. Also, provide more map info with procfs.
Chuck Cranor spurred on this improvement.
Fix a pseudo-swap leak problem. This mitigates "leaks" due to
freeing partial objects, not freeing entire objects didn't
free any of it. Simple fix to the map code.

Fixed syntax error for `make checkdpadd'. libfl.a should never be
used. ${LIBFL} is set to a weird value in an attempt to inhibit
its use, but only breaks properly in some contexts.
Fixed the usual style bugs for DPADD and LDADD (disorder, and += for the
initial assignment).
Don't build dependencies unless NOCLEAN is set. This speeds up
`make world' by about 14% here (down to 4490 seconds real on a
K6/233). Temporarily skip this optimization when building with
-j, since there are still many broken makefiles.
Fixed NOCLEANDIR option. Cleaning of `.depend' was broken.
Put -nostdinc in CFLAGS, not in CC, and don't override the default
CC. This fixes enforcing use of ${WORLDTMP}/usr/include.
Don't include ../Makefile.inc here. bsd.man.mk is always included
in another .mk file which has already included ../Makefile.inc, so
including ../Makefike.inc again mainly messed up `+=' definitions.
Fixed a bug where if MAXUSRARGS amount of args were passed in, the argv[]
array would end up without the NULL pointer termination, causing the glob
code to glob whatever garbage happend to follow on the stack.
Fixed `make -j9' by putting generated headers in ${SRCS}. Removed bogus
dependencies of generated .c files on generated headers (these made
`make -JN' work provided `depend' was made first). Sorted sources lists.
When all transformation rules to or from a suffix disappeared, make tries
to free the suffix. I think, it is a very strange idea. (Or, maybe, it is a
POSIX requirement?) And it is done incorrectly. Apparently, it even don't
update the list of known suffixes (but it is an other bug).
Jean-Simon Pendry's paper on amd refers to the use of "ypcat -k"
against the "master map" to get the list of mount point/amd map
correspondences, and using that list as command-line arguments to start
amd.
When I tried to do this with the existing /etc/rc* scripts, I found that
I couldn't do this by modifying only /etc/rc.conf: that file gets
sourced very early by /etc/rc, well before any networking functionality
is present, let alone NIS. Further, I wasn't able to figure out a way
to use various levels & types of quoting to defer evaluation of the
string to a point subsequent to NIS initialization.
As a result, I resorted to hacking /etc/rc.network -- but I did it in a
way that ought to be reasonably general, and avoid breakage for anyone
else.

Strengthen the rules governing the 127.0.0.0/8 subnet. The previous rules
allowed external hosts to send packets to the 127.0.0.0/8 subnet on the

Augment the last change after some deliberation with rgrimes & peter.
It is important that we keep the ability to send packets to a remote

that case.
Don't build shared libraries twice for `make world'. This reduces
`make world' times by about 10%. Use a new `bootstrap-libraries'
target to build just enough (static) libraries to bootstrap the
tools, and delay building of shared libraries until all the tools
have been built.
Fixed `/usr/bin/make world'. The version of `make' that we buildis
nand use is named "make", not ${MAKE}.

Ensure that TCP_REXMTVAL doesn't return a value less than t_rttmin. This

Fixed missing dependencies. The critical missing one was of bi-lexer.o
on bi-parser.h. Not having it sometimes (only with `make -j') triggered
a bug suite that led to ordinary cpp output being put in .depend files.
Various bugs (the main one only with `make -j') prevented timely detection
of failure to build and install gnu/usr.bin/cc. Eventually the missing
${WORLDTMP}/usr/libexec/cpp caused ${WORLDTMP}/usr/bin/cpp to be invoked
by cc, and this version of cpp is not suitable for such invocation.
Ordinary cpp output was put in .depend files when cpp terminated options
processing before seeing the -M flag.
