  Log:
  Because recalculate is only called once or twice for long sleeps,
  not every second forever while the process is sleeping, we have
  to manually call it to resynchronize p_cpbase on wakeup or it
  will wrap if the process was sleeping long enough (e.g. ~10 min
  with the ACPI timer) and really mess up the nticks calculation.
  
  The bug could very rarely result in an integer divide by 0 crash.
