Rather than "fixing" the encodings package, I'd rather suggest to
fix the unload procedure in the test suite. Some modules simply
should not be unloaded because it is known that the interpreter
needs them for internal purposes. In the case of the encodings
package it is not only the search function that gets kept alive, it's
also the codecs themselves which are cached by the implementation
How about following Fred's suggestion to run each test in a separate
process (possibly as an option to regrtest.py) ?!
