I am curious, what do you see when you strace it?
On Linux you get:
Darwin has no strace. dtruss is not very helpful:

That's where it hangs. If I manually send it SIGPROF, it cheerfully
continues:

But it doesn't send SIGPROF by itself. Looks like Darwin got screwed up
itimer implementation at least up to kernel 10.8.0, Mac OS X 10.6.8.
Didn't try it on Lion, maybe the have updated/fixed it.
