# XXX: This kind of problem can affect more than just encodings.
# In particular extension modules (such as _ssl) don't cope
# with reloading 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).
