New submission from john ryan <[email protected]>:
My test environment runs Ubuntu 18.04 in a virtualbox hosted on Windows 8.1 and
Python executes within a venv running Python 3.9.0 (Python 3.9.0 (default, Oct
26 2020, 09:02:51)
[GCC 7.5.0] on linux
Running a test with unittest.IsolatedAsyncioTestCase my code hung so I hit
ctrl-C twice to stop it and got the below traceback.
The really odd behaviour is that open is reported as not defined.
The behaviour is repeatable in my test, but I do not know how to produce a
simple test case. I do not know what the issue is with my code.
