pythongh-107184 introduced a refleak in test_import.SubinterpImportTests (specifically test_singlephase_check_with_setting_and_override and test_single_init_extension_compat). We fix it here by making sure _testsinglephase is removed from sys.modules whenever we clear the runtime's internal state for the module. The underlying problem is strictly contained in the internal function _PyImport_ClearExtension() (AKA _testinternalcapi.clear_extension()), which is only used in tests. (This also fixes an intermittent segfault introduced in the same place, in test_disallowed_reimport.) (cherry picked from commit 017f047) Co-authored-by: Eric Snow <[email protected]>
