Not sure that's the cause but I'm pretty sure initVM() needs to be
called from the main thread (for sure, the first call to
PyEval_InitThreads(), called by some JCC init code, needs to be).
I'm not near my computer until next week so I can't give your testcase
a try until then.

Here's an interesting issue:
