Hi Jeff,
I didn't wanna tease you, but for several machines I have seen, this
seems to be a general issue: iTunes, QuickTimePlayer or preview
playback is much more interrupted by other threads in Panther than in
Jaguar. Well, the QT playback is different from Core Audio and this
mail had to reach another list, but I only wanted to confirm, that some
CPU consuming action may interrupt easily QT Playback, which
disqualifies it for professional use.

Let's not be hasty in speculating on what might have happened and why.
Can you provide a bit more detail? Some of the questions that spring
to mind:
- What was iTunes doing prior to it freezing?
- What was Mail doing when the freeze happened?
- What hardware was involved here?
- What other apps were running and what were they doing?
- While hung, could other apps play sound?
- Can you make the hang happen again?
- If you can get it to happen again, getting a sample(1) trace of the
hang for iTunes, Mail and any other hung process would be helpful.

I'd like to put up a warning...
I just experienced, while having iTunes running, Mail.app made iTunes
freeze for more than half a minute.
OUCH! -There's something completely wrong with Mail.app. I don't know
if it's fixed for Panther, I'm using 10.2.8.
I believe that this has to do with some locking mechanism, to prevent
other applications writing in the files that Mail.app has open.
Indeed, this is insane, because then every application should
implement that kind of security. I believe it would be right to
implement it only while receiving mail over the network.
Anyway, I believe the solution is to keep Mail.app off computers that
need to process data in realtime.
-Did anyone else experience this?
