I agree.  We're interested in speed with these "functions" so I think that
an array makes sense.  For setlocale we could come up with some type of
scheme for block copying in changed sections as Mike suggests.

The only problem with this plan is that it doesn't accomodate ROMs or
read-only sections very well.  I don't know if that is an issue or not.
