[issue42848] asyncio produces an unexpected traceback with recursive __getattribute__

Didn't show enough of the traceback to show that the latter does not suppress the Test exception

Traceback (most recent call last):
  File "c:/Development/test/test.py", line 11, in bar
    x()
  File "c:/Development/test/test.py", line 7, in x
    raise Test('Hello World!')
__main__.Test: Hello World!

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "c:/Development/test/test.py", line 19, in <module>
    bar()
  File "c:/Development/test/test.py", line 14, in bar

    bar()
