I would be surprised if making a method call from a CoreAudio ioproc would cause an audio glitch even on slow computers. I had various levels of processing loads in CoreAudio ioprocs when I first started with CoreAudio and have gradually changed some things to lessen the load, but back I never experienced any audio glitches (even on a 500mhz G3).

Thanks for all the answers, everyone.

I'd already Sharked my code, and my ObjC methods were way down on the list of functions taking up time, so I had concluded that it's usually not a problem. I was, however, concerned that the cache scavenging could be something that might occur rarely, but when it did, could cause a glitch. That other people have some ObjC in their IOProc without glitches is reassuring.

It would be cool, though, if some low-level ObjC hacker on the list could give us a bit more info on the cache collecting. In particular, what triggers it and what thread does it happen on. Or if someone can point me to the source file, that would be fine too. Attempts to GTFW turned up no dice. Thanks.
