[issue6551] test_codecs fails when ran after test_zipimport and test_mailbox.

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

A simple solution could be to import encodings.ascii in regrtest.py,
before it saves the list of modules.

Or, since codecs are stored in a global cache dictionary that cannot be
cleared (interp->codec_search_cache), avoid unloading modules from the
encodings package.
