So, it could be that VM paging or Mail's disk IO is preventing
iTunes from getting at the audio data on the disk when it needs it.
There is no real time scheduling for disk I/O; so, the only totally
predictable way to make HD record and playback is put the audio on
it's own spindle (or multiple spindles if there are a lot of tracks).
This shouldn't be a surprise, that's the way everybody else has been
doing it...
VM paging would be the worst since it will additionally hold off the
HAL's IO thread which will cause glitches.
It shouldn't have a big impact unless the HAL I/O thread has
neglected to wire some of the memory it uses. Or are you thinking
that the disk interrupts for the paging will have that big an impact?
