Today I started a draft of a gaurdain to identify locklosses in which there was significant power build up in the arms, so that a check of the fast shutter should be run.  This is on the medm screens and is running, but there is no shutter check implemented yet.  The idea is that the state of this guardian this will be checked in our watchdog checker, and the ISC_LOCK guardian will require manual intervention to reset the state of this gaurdian before relocking the IFO.  This will be a reminder for the operator to run Stefan's shutter check ploting tool which is accessible from the bottom of the ISC guardian overview before manully resetting the state of this guardian so that you can relock.  Once we have an automated check this can all be automated. 

Since I didn't get a chance to check the arm power thresholds tonight, I will not integrate this into ISC_LOCK, so we are still relying on humans to check that the shutter closed.  This nominally means that if we get the interferometer locked we should set the request of ISC_LOCK to DOWN which will not unlock the interferometer but will preventing it from trying to relock automatically.  Hopefully this will be integrated soon.
