FreeBSD and OpenBSD don't support the signal(SIGCHLD, SIG_IGN) way of dealing with them. Wikipedia quote on the issue:

"POSIX.1-2001 allows a parent process to elect for the kernel to automatically reap child processes that terminate by setting the disposition of SIGCHLD to SIG_IGN or by setting the SA_NOCLDWAIT flag for the SIGCHLD signal; Linux 2.6 kernels adhere to this behavior while FreeBSD supports only the latter of these methods. Because of historical differences between System V and BSD behaviors with regard to ignoring SIGCHLD, calling wait remains the most portable paradigm for cleaning up after forked child processes."

A quick patch review: I played around with this and it seems to work fine in my testings and is a sound alternative to the current way of just ignoring the signal. If this solves issues for FreeBSD and OpenBSD I'm all for it. My thumbs up for applying this, Don and Spencer. :-)

Interesting. Thanks for taking the time to check this. _______________________________________________ xmonad mailing list xmonad@haskell.org http://www.haskell.org/mailman/listinfo/xmonad
