No, it all happens on the main thread.

This doesn't even happen in any part of my code. It happens within the 
Instant Messaging framework. After a bit more digging, I'm pretty 
convinced this is a garbage collection related issue, and I've filed a 
bug report.

...

In fact, I just had the bright idea to compile Mark Alldritt's iCheat 
Theater Demo with garbage collection turned on. And, although it isn't 
quite as eager to do it as my app, it eventually crashes with the same 
type of error. Just need to wiggle the mouse for a while while holding 
the window's resize knob. WIth GC off I can wiggle all I want for over 
a minute and every thing's just fine.

Thanks for the suggestions though.
