I ran into this the other day. I had put in hooks in the PyMemMALLOC to track memory per tasklet, and it crashed in those cases because it was being called without the GIL. My local patch was simply to not release the GIL. Clearly, calling PyMemMALLOC without the GIL is an API violation.

Indeed, this deserves fixing. (it would be better to still release the GIL around the low-level I/O call, of course)

Thanks Trent for finding this!

Antoine.
