Are you intending 2.3 compatibility, or would requiring Python 2.4 be
OK?  If you don't mind requiring 2.4, then I would use collections.deque
instead of using a standard list.

Also, I think that solves the general problem of having a string you can
append to cheaply, but I think it does so at the expense of some speed
in the specific problem of buffering.

Anyway, all this is a bit moot until I test it to make sure it solves
the speed issue on my repository.

Have fun (if at all possible),
