[Buildbot-devel] Multiple work directories based on branch causes SVN clobber

[Amber Yust]

This is most likely due to the following changeset:

https://github.com/buildbot/buildbot/commit/708852c170b483721fc79194ec351f6711af71e8

Since the .buildbot-sourcedata file is now in the builder base dir, instead
of in each src dir, it's no longer keeping two separate files, and thus each
build is overwriting the same file.
