[issue1147646] Windows deadlock with PyEval_ReleaseLock

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc amaur...@gmail.com added the comment:

This issue looks invalid to me: PyEval_ReleaseLock manipulates the interpreter 
lock, but not the thread state.
Both have to be released/reset before another thread can install its own thread 
state and run.

In other words, PyEval_SaveThread() should be used instead (and 
PyEval_RestoreThread() at the end, but the example code does not care to 
finalize the interpreter)
