Agreed. I'll fix this next week.

Some background: the first codec lookup done causes the encodings
package to be loaded which then registers the encodings package
codec search function. Then the 'ascii' codec is looked up
via the codec registry. All this takes time and should only
be done in case the code really uses codecs... (at least that
was the idea).
