  Log:
  As a temporary hack, turn off deferred preemptions that are the result of
  a fast interrupt handler doing an swi_sched().  This fixed the lockups I
  saw on my laptop when using xmms in KDE and on rwatson's MySQL benchmarks
  on SMP.  This will eventually be removed and/or modified when I figure out
  what the root cause is and fix that.
