Before, it was possible to get the following sequence of events (especially on Windows, where the C-level signal handler for SIGINT is run in a separate thread): - SIGINT arrives - trip_signal is called - trip_signal writes to the wakeup fd - the main thread wakes up from select()-or-equivalent - the main thread checks for pending signals, but doesn't see any - the main thread drains the wakeup fd - the main thread goes back to sleep - trip_signal sets is_tripped=1 and calls Py_AddPendingCall to notify the main thread the it should run the Python-level signal handler - the main thread doesn't notice because it's asleep This has been causing repeated failures in the Trio test suite: https://github.com/python-trio/trio/issues/119 (cherry picked from commit 4ae01496971624c75080431806ed1c08e00f22c7)
