/**
 * Reap all our dead children.  Sometimes libpurple forks off a separate
 * process to do some stuff.  When that process exits we are
 * informed about it so that we can call waitpid() and let it
 * stop being a zombie.
 *
 * We used to do this immediately when our signal handler was
 * called, but because of GStreamer we now wait one second before
 * reaping anything.  Why?  For some reason GStreamer fork()s
 * during their initialization process.  I don't understand why...
 * but they do it, and there's nothing we can do about it.
 *
 * Anyway, so then GStreamer waits for its child to die and then
 * it continues with the initialization process.  This means that
 * we have a race condition where GStreamer is waitpid()ing for its
 * child to die and we're catching the SIGCHLD signal.  If GStreamer
 * is awarded the zombied process then everything is ok.  But if libpurple
 * reaps the zombie process then the GStreamer initialization sequence
 * fails.
 *
 * So the ugly solution is to wait a second to give GStreamer time to
 * reap that bad boy.
 *
 * GStreamer 0.10.10 and newer have a gst_register_fork_set_enabled()
 * function that can be called by applications to disable forking
 * during initialization.  But it's not in 0.10.0, so we shouldn't
 * use it.
 *
 * All of this child process reaping stuff is currently only used for
 * processes that were forked to play sounds.  It's not needed for
 * forked DNS child, which have their own waitpid() call.  It might
 * be wise to move this code into gtksound.c.
