This writes to stdout here - isn't that as bad as the other print we are avoiding?

This happens before the cnd_signal below.. the main thread waits for that signal before exiting so anything before that is fine.

I ran this test continuously for over an hour (while running the whole test suite in the background to cause contention for cpu cores) and i didn't timeout at all.. so I'm pretty sure this test is fixed now. |

This time I'm pretty sure the deadlock no longer
occurs. The issue was the pthread key destcrutor
was calling printf.
Again this doesn't fix the actual issues but avoids
hitting it this test.
