Enable faulthandler

[drew2a]

This PR addresses frozen test problems and enables faulthandler in the hope it can print the stacktrace of frozen tests.

It passes the following test:

@pytest.mark.timeout(1)
def test_block():
    #  This is an example of breaking the `@pytest.mark.timeout(1)`. Just run the test.
    def block_forever():
        while True:
            pass

    blocker = threading.Thread(target=block_forever)
    blocker.start()
    blocker.join()  # This join will block the event loop indefinitely

with the following stacktrace:

Timeout (0:00:15)!
