  Log:
  Dot the i's:
  1  Move the debug.clock_adjust_* sysctls to debug.clock.adjust_* to
     make it easier to get only the clock statistics.
  2  Make the sysctls read-only [suggested by Marius].
  3  When determining the new clock adjustment, we checked for an error
     either larger than 12.5% or smaller than 12.5%. We left out an error
     of exactly 12.5%. For errors larger than 12.5% we adjust the clock
     reload value in such a way that the next clock interrupt would be
     early (as in premature). For errors less than 12.5% we stopped the
     adjustment.
     The current algorithm doesn't benefit from excluding an error of
     exactly 12.5%. Change the code to stop adjusting the clock if the
     error is *not* larger than 12.5% [suggested by Marius].
