      * Remove doubleFork, handle SIGCHLD
        This is a rather big change.  Rather than make spawned processes
        become children of init, we handle them in xmonad.  As a side effect
        of this change, we never need to use waitForProcess in any contrib
        module -- in fact, doing so will raise an exception.  The main
        benefit to handling SIGCHLD is that xmonad can now be started with
        'exec', and will correctly clean up after inherited child processes.
