Thanks everybody for the replies so far. I think I'll have a look at thread affinity tags first.

Why do you think restricting threads to run on only 2 cores will be useful?

I observed problems with GUI threads when running the app on an 8- core Mac Pro, while it runs fine on dual core CPUs and PPC. The fix is intented as a temporary workaround only until I found the real cause.

That's your problem. All of your GUI (with a few exceptions) needs to be on the main thread.
