[Buildbot-devel] Killing running build automatically

This is a good question about a frequent problem.

Buildbot has the "TreeStableTimer" parameter that you can add to a
BranchScheduler that will delay a little bit the builds until no change is
seen on the branch for a certain amount of time.

The drawback is that it takes a little bit of time before a build start
after the change has been uploaded.
I think you idea of cancelling the current builds and buildrequests for
parent changes is a good idea, but this is something that has to be
implemented. Note that this will also have the drawback of cancelling
actual work done, and reducing the traceability of which change is
responsible for a build failure.
