Dunno, but we'll hash that out on the python-crypto list.  For now I
just wanted to know if parametrized codecs would be an inherently bad
idea.

(Two ways of handling this would be requiring all write() calls to use
a multiple of the block size, or reporting an error on the close() if
you haven't written out an even number of blocks.  I have no idea
which is preferable; not sure I like either of them...)
