I don't know, but you could certainly try it yourself if you really wanted
the answer.  I have personally observed Windows 2000 going out to lunch
for 100 - 200mS at a time for no apparent reason.  One of my customers was
(despite my advice) trying to use Windows 2000 to control some industrial
equipment with a loop time of 30mS.  It worked fine most of the time, and
the CPU useage was only a few percent, but there was a hiccup every once
in a while.  Despite shutting down all other processes we knew about,
making sure there was plenty of real memory, etc, it would still happen
every few minutes to every few seconds.  The probability of occurrence
could be greatly increased by just dragging the mouse around without
hitting any buttons, even over the desktop.
