I definitely don't want to continue the old habit of having a slow and a fast module with different names; the experience with especially cPickle and cStringIO is that everyone believes their code is performance critical and hence uses the C version if it exists, thereby repeating the same idiom over and over.

Actually, I am been surprised myself that the C version of StringIO isn't always faster than the Python one. I have a testcase where using StringIO, instead of cStringIO, is ~20% faster.
