…afety. (pythonGH-18786) `list(sys.modules.items())` was apparently not immune to "dictionary changed size during iteration" errors. Tested internally using an integration test that has run into this a couple of times in the past two years. With this patch applied, the test is no longer flaky. (cherry picked from commit 85cf1d5) Co-authored-by: Gregory P. Smith <[email protected]>
