While the IFO was held in the DOWN state, Shiela (while I watched) accepted all SDF differences for whichever SDF file they were currently comparing against. This brute force, half-reconciliation should get us some of the way toward an easier recovery after the power outage this weekend.

Thing we need to make SDF more maintainable:
1) Remove the distinction between SAFE and DOWN for SUS and SEI. Because SEI and SUS come up with the watchdog tripped, and the start up state for both systems guardian has the masterswitch off, there's no difference between these states. 
2) A rapid way to assess and change a group of front-end model's SDF reference files. I.e. we should be able to switch between OBSERVE and DOWN quickly instead of having the 4 screen, 15 clicks per front-end process it is now.
3) A easy, built in way to find out what channels of a given front-end are controlled by all guardians, such that we can un-monitor them.
4) A much easier way to reconcile non-initialized and not-found channels than the still-confusing SDF Save and SDF Restore screens.
