Whoa, this was a tough one. But now i know about --with-pydebug and a few
other things.

Python only releases the GIL every once in a while
and my test code used only one instruction that held the GIL in the main
thread. It dawned on me after watching backtraces of acquire/release
locks of the working/not working versions.
