description:
- Do not lower interrupt level at clock interrupt.
  The original code lowers level 6 to 4, and if a
  clock interrupt occurs in splzs (or similar) the
  system may be in unpredictable state.
  To do such a hack correctly, checking the original priority
  and duplicated clock interrupts would be required.
  For now, just disable the hack.

- Do not use clock interrupt for ms polling.
