We don't use tools-shadow in any meaningful way; it's apparently neither set up to automatically take over nor, from judging of the past experience, it's likely that we need some hot fail-over as most (all?) SGE snafus were not related to a failure in tools-master, but FS failures, a confused exec node, etc. Taking tools-shadow out of the game should reduce complexity.
