Scheduler patch 03 available for testing

[Matthew Dillon]

    Ok, a more refined scheduler patch is now available for testing:

	http://leaf.dragonflybsd.org/~dillon/sched03.patch

    It fixes the ^Z bug that was in 02 and I've done some moderate testing
    on both UP and MP systems.  Apart from fixing the bug I bumped up the
    p_interactive field's effect on scheduling a little.
