It is possible to recursively destroy snapshots even if the snapshot

We can execute:
# zfs destroy -t tank@snap

Unfortunately it is not possible to do the same with recursive rename:

The code in clear_remove() and clear_inodedeps() skips one entry
in the pagedep and inodedep hash tables. An entry in the table is
skipped because 'pagedep_hash' and 'inodedep_hash' hold the size
of the hash tables - 1.
The chance that this would have any operational failure is extremely
unlikely. These funtions only need to find a single entry and are
only called when there are too many entries. The chance that they
would fail because all the entries are on the single skipped hash
chain are remote.

Ensure make -j N universe works correctly, by checking for an up-to-date
make before starting the universe targets themselves. Otherwise, all of
the targets would attempt to build make simultaneously, overwriting each
other's copies of the make object files and executable. This could lead
to strange errors, for example when partially-written make executables
are invoked.
Also amend r216620, to make the rest of universe wait properly until the
upgrade_checks target is finished, by adding universe_${target}_prologue
to the .ORDER target. Otherwise, make will be too smart for its own
good, and start building the universe targets simultaneously with the
prologues anyway.
FreeBSD 8.0 introduced inpcb reference counting, and FreeBSD 8.1 began using
that reference count to protect inpcb stability in udp_pcblist() and other
monitoring functions, preventing the inpcb from being garbage collected
across potentially sleeping copyout() operations despite the inpcb zone
becoming shrinkable.
However, this introduced a race condition in which inp->inp_socket() might
become NULL as a result of the socket being freed, but before the inpcb we
removed from the global list of connections, allowing it to be exposed to a
third thread invoking udp_input() or udp6_input() which would try to
indirect through inp_socket without testing it for NULL. This might occur
with particular regularity on systems that frequently run netstat, or which
use SNMP for connection monitoring.
Later FreeBSD releases use a different reference/destruction model, but
stable/8 remained affected in FreeBSD 8.2 and 8.3; the problem could be
spotted on very high-load UDP services, such as top-level name servers.
An Errata Note for 8.x branches under continuing support might be
appropriate. Regardless, this fix should be merged to releng/8.4 prior to
8.4-RELEASE.
