    C{shutdown} doesn't return immediately when a time specification is
    provided.  Failures are reported immediately after it starts and return a
    non-zero exit code.  The process protocol calls C{shutdown} and waits for
    failures for C{timeout} seconds.  If no failures are reported it fires
    C{result}'s callback with whatever output was received from the process.
    If failures are reported C{result}'s errback is fired.

    @ivar result: A L{Deferred} fired when C{shutdown} fails or
        succeeds.
    @ivar reboot: A flag indicating whether a shutdown or reboot should be
        performed.  Default is C{False}.
    @ivar delay: The time in seconds from now to schedule the shutdown.
        Default is 240 seconds.  The time will be converted to minutes using
        integer division when passed to C{shutdown}.
