It doesn't seem likely to me.  If a process is looping in futex() it is 
probably waiting for another processor to release a spin lock.

pagefault_enable


I hope this patch will "fix" a performance problem I'm seeing.
Occasionally a JVM will get stuck in futex() using a full engine
yet not doing any work.  Is it pagefault related?
