It's actually probably even more subtle. My experience has been that
cdrdao causes problems but cdrecord doesn't. I also noticed a similar
effect recently when copying a large number of CDs to disk (several
hundred), on a couple of occasions a timeout caused DMA to become disabled
on the CDrom drive and when that happened the clock started running slow.
