Hmm, it seems at least one person on current@ was already confused by this and 
asking if he should turn on FULL_PREEMPTION instead.  We probably don't want 
people doing that. :-P  Also, believe me that I haven't forgotten about the 
preemption stability problems.  I just need to reproduce these problems on 
machines with a serial console.  The only machine I can reproduce hangs on so 
far is my laptop which has no serial port. :(
