At that point there should be exactly one child process (the sleep
that is being killed), so there shouldn't be any confusion between
waiting for a foreground job and waiting for that background job.

So it must somehow be the case that the SIGCHLD has been received
(post-kill) but the jobtab state of the sleep process did not get
properly updated; and now zsh is in an infinite (but not busy, as
it stops each pass in sigsuspend()) loop looking for a new SIGCHLD
followed by a state change of that process, which is never going to
happen.

I'll be curious to see if the patch from 33531 changes this at all.
