  Log:
  Revert most of 1.109.  Although it improved the situation on one particular
  motherboard, in practice the changes resulted in many false positives for
  heavy network loads, etc. resulting in poor performance.  Also, the
  motherboard referenced in the 1.109 log has other problems and simply does
  not seem to work with the APIC enabled even with the changes in 1.109.  The
  correct fix for that board seems to be to not use the APIC at all.  One
  thing kept from 1.109 is that throttled interrupts are now effectively
  polled on every clock tick rather than just 10 times per second.
