This change is a companion to r60148 which already successfully dealt with a similar issue on thread shutdown. In particular this loop has been observed happening from this call path: #0 in find_key () #1 in PyThread_set_key_value () #2 in _PyGILState_NoteThreadState () #3 in PyThreadState_New () #4 in t_bootstrap () #5 in pthread_start_thread () I don't know how this happens but it does, *very* rarely. On more than one hardware platform. I have not been able to reproduce it manually. (A flaky mutex implementation on the system in question is one hypothesis). As with r60148, the spinning we managed to observe in the wild was due to a single list element pointing back upon itself.
