	* app/main.c: removed SIGCHLD handler which used to call
	waitpid(-1,...) because this breaks all waitpid(pid,...) calls
	in a non-deterministic way. Apparently it is possible to use both
	SIG_DFL *and* SA_RESTART (SA_RESTART being the original reason
	why the call to sigaction() was introduced).

	* app/plug-in/plug-in.c (plug_in_close): don't have a million
	subsequent if(plug_in->pid) blocks. Put everything into one big
	if(plug_in->pid) block instead. Call g_spawn_close_pid() on all
	platforms instead of using the Win32 CloseHandle().
