The below part from Core.hs is completely wrong, you can't just ignore SIGCHLD and hope for some deity cleaning up the mess. And, BTW the default action of SIGCHLD is SIG_IGN, so both calls of `installHandler sigCHLD ...' are equivalent (and thus bogus).
On a system conforming to POSIX.1-2001, you just can. The easy solution would be to call sigaction with the SA_NOCLDWAIT flag, but System.Posix.Signals lacks the interface to do this :-(. Maybe we should just add that silly wait-loop sigchld handler. Regards, -- Tomáš Janoušek, a.k.a. Liskni_si, http://work.lisk.in/
