[New-bugs-announce] [issue14084] test_imp resource leak

[Stefan Krah]

New submission from Stefan Krah <stefan-usenet at bytereef.org>:

I tried to reproduce the failure from #14080 using this:

./python -m test -uall -v -F test_imp


After around 500 iterations the test fails:


======================================================================

  File "/home/stefan/pydev/cpython/Lib/test/test_imp.py", line 58, in test_find_module_encoding
