Ah I missed the WIFSTOPPED check above.  The case I was thinking was "what if we
get a WIFSTOPPED for a deleted zombie leader, that would probably be some problem
in the kernel, we don't want to add it back".  And I didn't think about WSIGNALED.

So effectively, I was proposing to have:

else if (WIFSIGNALED (status) || WIFEXITED (status)

instead of an "else".  But given that WIFSIGNALED and WIFEXITED are the only
plausible alternatives to WIFSTOPPED, it's not really necessary.
