The DELAY() in the calibration of the P^H586 clock is not very accurate.
No one knows exactly why (especially ones that don't have a 586 and
have an accurate a DELAY() as can be expected :-).  The recent decrease of
the calibration delay from 1 second to 4 ticks is not likely to have
helped.

microtime() using the 586 clock should be almost immune even to the
scheduling clock frequency somehow becoming wrong.
