highest ID rather than the highest timestamp. Otherwise, if a build from revision N finishes after a build from revision N + 1, then the build from revision N will end up in the channel. Thus, the channel contents will be out of sync. This is still not quite correct: if a revision *reverts* to an older build, the channel will still end up out of sync, because Hydra won't schedule the build again (after all, it has already done it). A better fix would be to add a separate timestamp denoting when the build was last "current" (i.e. corresponding to the "head revision" of its job).
