Doesn't forking without RFNOWAIT interfere with the job handling
mechanism in rundir? The new call to waitpid can consume the
waitmsg from an unrelated proc and return before the send in
returnmail finishes.
I haven't run this new code, only read it. Am I missing something?
Cheers,
Anthony

I think you're right; I was the one that removed the RFNOWAIT
in the first place, in 49d7ca8d92e5667f3e5ece4c6acbc1064701e2f8
I'll revert for now.
It'd be really handy to have a `waitfor(pid)` function.
