Well, I'm working on two related projects, pyaba and pyArch.  Every so 
often, I take some code that pyaba uses, and move it into pyArch.  It 
would be nice to associate the patches produced by these two commits, 
since failure to update both will screw things up.  Similar issues come 
up with hackerlab every so often.

If we want really good perfomance, we need to support pipelined 
operations properly.  We also need an WebDAV library that supports 
pipelining.

Mixed versions and commit --base will solve this nicely.  In the 
meantime, there's "aba rebase".
