[New-bugs-announce] [issue22910] test_pydoc test_synopsis_sourceless is a flaky test

[Gregory P. Smith]

New submission from Gregory P. Smith:

When running a parallel make -j12 test, test_pydoc fails reasonably often with:

test test_pydoc failed -- Traceback (most recent call last):
  File "/.../Lib/test/test_pydoc.py", line 556, in test_synopsis_sourceless   
    synopsis = pydoc.synopsis(filename)
  File "/.../Lib/pydoc.py", line 240, in synopsis
    mtime = os.stat(filename).st_mtime
FileNotFoundError: [Errno 2] No such file or directory: '/.../Lib/__pycache__/os.cpython-34.pyc'

Two other issues mention this failure as being introduced recently in comments:
