I was aware of that.  I haven't done it systematically so far, but I
really should do it to reduce the startup overhead.  I suspect 'bzr
version' takes several times as long as it should because it loads a lot
of modules.  (Not that bzr version really matters but there are other
cases which do.)

Is there anything else we can do in the future to reduce the startup
time?
