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. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
