"mode='update'" should only take a long time on the initial checkout,  
or if a change happens on another branch (Buildbot only keeps one  
working copy around).

If the slowdown is due to changing branches, you may be interested in  
this patch:

http://buildbot.net/trac/ticket/97

But in that case, you may want "mode='copy'" to avoid the problem that  
Dustin describes in the last comment there.
