Subject: gh-69605: In test_pyrepl.test_already_imported*, invalidate FS import caches (#143436)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4f9a8d075ee52b8f56aca14102c8bf9fd6f3c512;p=thirdparty%2FPython%2Fcpython.git

gh-69605: In test_pyrepl.test_already_imported*, invalidate FS import caches (#143436)

This makes the test robust against file systems with low timestamp resolution, which otherwise would fail to re-import in the tight loop of the test.
