cpython-lru_cache-weakref: Python/thread

annotate Python/thread_cthread.h @ 20468:ebfd87e87884 legacy-trunk

Partial patch from SF #452266, by Jason Petrone. This changes Pythread_start_thread() to return the thread ID, or -1 for an error. (It's technically an incompatible API change, but I doubt anyone calls it.)
