Nu uh.  Nor can I do anything about restarting system calls after the
signal handler returns :-( wish I could, or alternatively, shoot the bozos
who write code that depends on this functionality).  And watch out for
possible semantic differences in "handling" SIGCLD and SIGCHLD (check your
man pages.)

"quick hack" means exactly that.  It works - most of the time - for most
purposes (in my experience)
