That would be great, see

http://doc.bazaar-vcs.org/bzr.dev/developers/profiling.html
and
http://doc.bazaar-vcs.org/bzr.dev/en/developer-guide/HACKING.html

I believe the main problem is that we are processing the whole graph
to work out which revisions merged which others.  (which hg and git do
not do, iiuc.)  For even quite active trees this is good, but emacs
has a lot of history.

In this case you probably just want the last ten direct commits, bzr
log --line -l10.  mwh posted a patch to improve this and there is some
more that can be done.
