Option 1) Call PyEval_ThreadsInitialized() in PyGilState_Release(). Non-invasive, but bleh.
Tim rejected this option back when PyEval_ThreadsInitialized() was added to the API [1]. Gustavo was having a similar problem with pygtk, and the end result was to add the ThreadsInitialized API so that pygtk could make its own check without slowing down the default case in the core.
Option 2) Call PyEval_SaveThread() instead of PyEval_ReleaseThread()[1] in PyGilState_Release(). This is my favourite option (PyGilState_Ensure() calls PyEval_RestoreThread which is PyEval_SaveThread()s "mate") and I guess you can distill this long mail into the question "why doesn't PyGilState_Release do this already?"
See above. Although I'm now wondering about the opposite question: Why doesn't PyGilState_Ensure use PyEval_AcquireThread? Cheers, Nick.
