MIDIClientCreate() Hangs in 10.7.x?

Hey Folks,

I just filed rdar://11121989 to track this, but any advance help would be greatly appreciated.

In a nutshell, users are reporting that Capo is hanging for them in rare circumstances. Sample logs have all pointed the finger at a hung MIDIClientCreate() call. This only seems to have popped up recently -- users have not reported the issue in a version earlier than 10.7.2.

I can't imagine that anything I'm doing is causing this to hang, as I simply pass MIDIClientCreate() a pointer to my callback, and a context pointer. As I understand it, this method simply registers my information into a table of callbacks via a mach call.

4 of my users' samples can be found here (and attached to the radar, for Apple folks):

Is there any kind of workaround that I can put into my code, or ask my users to do when they get stuck in this situation? I'm not sure that a restart clears it up for them…

Thanks in advance,

Chris Liscio
