    Move SIGUSR1 notification as late as possible.

    If we inherited a signal mask from the parent process that ignores SIGUSR1,
    then we will send SIGUSR1 to the parent to indicate when we're ready to
    accept connections.  Unfortunately, we send this notification way too
    early, right after creating the sockets rather than just before entering
    the main loop.

    Move it to just before Dispatch() so we're not lying quite so much.
