John,
Thanks for your concise explanation - I am familar with drivers and
interrupts so I can see both the need for interrupt prevention and the
problem with two lost interrupts. It's been a long time since I looked,
but as I recall the CMOS clock doesn't have milliseconds - what a pity!

Well, while we may not be able to control how well drivers are written,
perhaps we could document drivers and software known to cause problems?
I'll start the list:
- Sun's Java Virtual Machine
Needs to be started with the "-XX:+ForceTimeHighResolution" parameter to
avoid loosing interrupts.
See:

Perhaps this could be added to the documentation?
Cheers,
David
