By the way, this is a *perfect* example of the kind of
inter-repository build coordination (trac keyword 'buildcoord') I'd
like to see added to Buildbot.  I think the natural solution here is
to have a SourceStamp that specifies { 'thing-one' : 'sha1-one',
'thing-two' : 'sha1-two', .. }, and then some way for each git step to
extract its appropriate revision.

This isn't something that's in development at the moment, but it's an
interesting idea.
