Thanks for sharing your tips; also noteworthy, this tip by Martin Pool:

Actually, I have a cron jobs which pushes the revisions of the 4.4
branch in the 4.5 repo on Launchpad; I just realized that this was
still an issue from your email, so I've looked at the script again and
it wasn't dealing with 4.6; I've added a step to copy the 4.6 revs into
the 4.5 repo every night, so that should make bzr push fast again for
you. (I'm still pushing the revs though, will take a while.)

I don't :-)

bzr has plugins to merge changelog entries for some types of
changelogs; I wonder whether we could use these here. Another option
would be to generate a GNU ChangeLog from the bzr log at release time
as we do for linaro-image-tools for instance.
