On my pipelined support, which redid some of the effbot.org stuff to
keep a queue of things to work on, and required keep-alive support (so
it didn't work with HTTP1.0 servers), I saw at least a 2:1 improvement
in 'bzr get' time.

But that was back before weaves, so I would expect the improvement to be
a little bit less.
