I've test your changes (r20579 with r20601,20605,20606).
KeAbortWaitThread is called for waiting threads only. But I'm running in
another problem. Compiling ros on ros (with the nice parameter '-j2')
hangs after some time. If I look to taskmgr or ctm, only the idle thread
consumes cpu power. Sometimes I can stop the compiling with Ctrl-C,
sometimes not. I wasn't able to compile ros on the smp machine. On the
up machine, one of four compile runs does finish.
