Hi Jeff,
Thanks for pointing out Sampler, after I sent you the trace I was
looking through and noticed what was hanging it up.
I've never used it before, so I highly recommend it for those who
haven't tried it out.

I'd need to see the stacks for all the threads in the process to give
you some idea of what's going on. The best tool for this is sample
rather than gdb.
At any rate, all this stack is saying is that the thread adding the
IOProc is blocked waiting for to synchronize against the IO thread. If
I had to guess, I'd say that the IO thread is probably blocked in some
IOProc when the call to add another IOProc came in. Seeing all the
other stacks in the app would say for sure.
