Let's say, port A depends recursively in this order on B, C, D; port E depends on C and D. The buildbot builds binaries for A and E. Then C gets a commit, which might be scheduled in the buildbot or not. Next I try to get the binary for A. Do I get the binary for D and rebuild C, B and A locally? Does my request trigger any action for the buildbot to rebuild A, B, C and eventually E?
