* get rid of zombies in a more portable way
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."
