PLEASE TEST: IPI deadlock avoidance patch

[Julian Elischer]

heh..

My partial diagnosis is that there is another SMP related problem that 
you can not tickle
without the IPI patch, because you can not stay up long enough..

Looking at the IPI patch, it is almost impossible to imagine a scenario
where it itself could cause data corruption.
