With 0.7.8, you'll get scheduler properties, that is, you can create
two schedulers that are going to set different build properties when
kicking off the build.

You can then add a clobber step which would SKIP for depend builds,
based on those set properties.

To build each change, you need to subclass the scheduler, and send out
subclasses subclassed SourceStamps in the build requests, and I don't
see us fixing that for 0.7.8, sadly.
has sample code. http://buildbot.net/trac/ticket/288 is the ticket for
making this better.
