Today, I was planning to introduce the LASER_PWR Guardian node and the management changes in ISC_LOCK and ALIGN_IFO that would go along with it, but maintenance day got in the way. The LASER_PWR node seemed to work well and I thought I ironed out the small issues I had with the management, but I had not made it all the way through initial alignment before front ends started crashing and the PSL went down. I reverted to the copies in the svn just before I began my work (I committed before I started in case something like this happened), and it seems to all be back to mornal.

I'm leaving the LASER_PWR node alive, but stopped.
