Very interesting. Have you made measurements to see how many times you
lost one of your cycles. I made these kind of measurements on Linux using
the real-time clock with C and it was very interesting (
http://www.gael-varoquaux.info/computers/real-time ). I want to redo them
with Python, as I except to have similar results with Python. It would be
interesting to see how Windows fits in the picture (I know nothing about
Windows, so I really can't make measurements on Windows).

Cheers,
