--- Comment #1 from Jilles Tjoelker <jilles at FreeBSD.org> ---
Hmm, this is sort of a workaround for the shell reaping zombies quickly and not
providing the script with a good way to detect this.
If code is executed like
sh -c '...; exec pwait $$'
it arguably should deadlock.
The patch seems a simple way to avoid the deadlock in poudriere, though.
