| I think you should write the test suite in terms of bytes.

The problem is that pybsddb must work in python 2.3, 2.4, 2.5, 2.6 and 3.0.

My final approach was to write some proxy/adapter objects to manage the
unicode<->bytes conversion, so being able to share testsuite and
basecode between all pybsddb supported platforms.

Not the nicest thing to do, but the the bulk of code is unchanged and
fully shared in any supported python version. The adapter code is big,
but isolated.

Some code would be simplest if pybsddb classes allowed subclassing. This
is in my "todo" list.
