Thanks for fixing this, BTW.

@pablogsal, leak tests didn't catch this because we use the "raw" domain to allocate PyThreadState and PyInterpreterState.

Oh interesting, can you confirm that changing the domain to memory makes the test fail?

Fatal Python error: _PyMem_DebugCalloc: Python memory allocator called without holding the GIL
Python runtime state: preinitialized
