# XXX: This kind of problem can affect more than just encodings. In particular
# extension modules (such as _ssl) don't cope with releoding properly.
# Really, test modules should be cleaning out the test specific modules they
# know they added (ala test_runpy) rather than relying on this function (as
# test_importhooks and test_pkg do currently).
# Implicitly imported *real* modules should be left alone (see issue 10556).
