Be aware that OS/2 allows you to read a high-resolution timer.
The calls are:

  DosTmrQueryFreq and
  DosTmrQueryTime

They are not documented, but they are prototyped in BSEDOS.H
EXTRA uses these calls to time your functions when you are
using a trace.  These calls have around a microsecond resolution.
