If you want to throw your debugger at it, there's an existing
subinterpreter test case in _testembed that should exhibit any
Initialize/Finalize leaks:
https://github.com/python/cpython/blob/master/Programs/_testembed.c#L36
However, if there is one, our existing automated leak monitoring
unfortunately wouldn't pick it up, as the embedding tests run in a
subprocess rather than the main test process.
Cheers,
Nick.
