--- Comment #4 from Jilles Tjoelker <jil...@freebsd.org> ---
As noted by the pwait(1) man page, pwait is not a replacement for the wait
builtin, since it can wait for a process to terminate and show the exit status
but cannot clean up zombies or state on the parent process. Therefore, I don't
think the wait builtin should be changed -- if a script wants to wait for an
unrelated process, it can use pwait.
rc.subr already uses pwait when waiting for a service to stop. This does not
work optimally because pwait waits for a process to terminate, while rc.subr
wants to wait for the zombie to be reaped by the parent such as init (by
waiting until kill -0 PID fails).
