Log Message:
The interrupt handler needs to clear the interrupt condition
before re-arming the timer. Otherwise the timer could expire
again before clearing the interrupt, the interrupt gets lost
and the clock stops.

On real hardware that could only occur if the timer interval
is extremely short or if there is a higher-than-clock interrupt
that delays processing. In the emulated world however, time
can progress non-continously and this happens often under load.
