With Vista that happens too. People report pauses of up to 15 seconds. They
have a problem with the scheduler and this was acknowledged by Microsoft about
a year ago:

Let me see if I can quickly find an example.
Okay, I spend like 30 seconds on it. I couldn't find the example I had in mind,
but I found this:
