 We hit an issue on a master recently where a reconfig failed part way
 through and caused a bunch of our custom code to have bad references in
 it. In turn, this caused a great number of builds to fail with a
 setupBuild exception. Even when a setupBuild exception occurs for another
 reason it really sucks that the builds never start and are never retried.
 I think that Buildbot should either retry them automatically are make it a
 lot easier to retry them.

 Because the builds never started we wouldn't be able to make use of the
 RETRY status to make this happen. I was chatting with Catlee about this
 and he suggested that we might be able to accomplish this by running
 newBuild() in a try/except block and resetting claimed_at/claimed_by if it
 fails, possibly after waiting some period of time.
