o Terminate an endless loop sh -T goes into in dowait() around waitproc().

XXX from Tor: "The shell can also go into a similar loop if the child was
killed by signal 127, since the shell would believe the child to have
only stopped (WIFSTOPPED() macro returns nonzero value).  Disallowing
signals 127 and 128 will fix that problem."  See kern/19402 for details.
