____________________ TestStreamReader.test_ctor_global_loop ____________________
[XPASS(strict)] No idea why ClientRequest() is constructed out of loop but it calls `asyncio.get_event_loop()`
__________________________ test_set_loop_default_loop __________________________
[XPASS(strict)] No idea why _set_loop() is constructed out of loop but it calls `asyncio.get_event_loop()`
