It's the usual reason my spambayes popproxy dies. I can't recell seeing it before on Windows or while running the test suite.
Don't debug builds route all PyMem_ calls through PyMalloc? Doesn't pymalloc rely on the GIL being held when it's called? If both of these are true, there's an obvious problem here, because the call to PyMem_NEW in PyThreadState_New certainly isn't called with the GIL held...
This would only be a problem in a debug build, though.
Cheers, mwh
