Unfortunately, converting to ``unicode`` instead of ``str`` is very
expensive. This will probably change to some extent in Python 3.0.

Checking for a ``__unicode__`` attribute helps some, but it's still
about 15-20% slowdown on the admittedly not very realistic bigtable

I think we need to depart from this idea.

I did refactor the code generation logic to make it easier to test
these things quickly; it's now located in the ``generation`` module.
