The guardian upgrade has been completely aborted, due to the unexplained segfaults described in elog thread 40765 .  The entire guardian system is back to the exact same configuration as it was two weeks ago (guardian 1.0.3, h1guardian0 ubuntu12).  All nodes are up and running nominally.

h1guardian1 has been left in place to run demon excision tests: 20 fake guardian nodes are running under valgrind in the hope of catching a crash that would point to the problem.  These tests should not affect interferometer operation in any way.
