[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

3 tests of test_contextlib_async logs messages. I would prefer a quiet output.

test_contextmanager_trap_second_yield (test.test_contextlib_async.AsyncContextManagerTestCase) ... 
Task was destroyed but it is pending!
task: <Task pending name='Task-12' coro=<<async_generator_athrow without __name__>()>>
ok

test_contextmanager_trap_yield_after_throw (test.test_contextlib_async.AsyncContextManagerTestCase) ... 
Task was destroyed but it is pending!
task: <Task pending name='Task-14' coro=<<async_generator_athrow without __name__>()>>
ok

test_async_gen_propagates_generator_exit (test.test_contextlib_async.TestAbstractAsyncContextManager) ... 
Task was destroyed but it is pending!
task: <Task pending name='Task-20' coro=<<async_generator_athrow without __name__>()>>
ok

Current output:
