You could run one per branch, but what is happening here is that the  
default svn_watcher.py is not giving the Buildbot schedulers any  
information on the branch where the change was made.

The SVNPoller class allows you to describe your particular URL  
structure (e.g. trunk/, branches/<branch_name>) via the split_file  
parameter:

Once the change knows about the branch name, then the branch-related  
parameters to the Schedulers will have an effect:
