Excellent! The problem lay in attempting to keep the two Windows clocks
in synch, and one monotonically increasing. If one task called Clock, and
that caused a resynch, then Base_Ticks, but not Base_Monotonic_Clock,
would be reset, thus causing a backward movement of Monotonic_Clock, and a
consequent increase in any other task's outstanding "delay"s. Perhaps OS2
doesn't have such a mess. The symptom was that in a multitasking program
where one task called Clock, and one of the clocks was adjusted manually or
automatically, another task's "delay" would be markedly lengthened.

I just sent it in Saturday.
