  Log:
  Tweak the lapic timer code to get the performance closer to the pre-lapic
  timer case:
  - Remove the virtual fooclock interrupt counters as they have served their
    purpose.
  - Adjust the dividers for the different clock such that profhz is now a
    multiple of stathz as in the non-lapic case, and the timer now runs at
    hz * 2 rather than hz * 3.  With the new divisors, the default clock
    rates are:
  
    kern.clockrate: { hz = 1000, tick = 1000, profhz = 666, stathz = 133 }
