bpo-30807: signal.setitimer() now uses _PyTime API (GH-3865)
...
The _PyTime API handles detects overflow and is well tested.
Document that the signal will only be sent once if internal is equal
to zero.

bpo-30038: fix race condition in signal delivery + wakeup fd ( #1082 )
...
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:

raise InterruptedError anymore if it is interrupted by a signal not in its
sigset parameter.
