Shutdown thermcopoly1 SNF 2008-03-01 16:10:05: failed leak

[ericp at snf.stanford.edu]

Failed leakcheck in pump recipe (STBYPOLY). 
After MAryam's run, it failed out of the pump program. 
I re-ran the pump program, and watched it: 
It got to base (I observed it go to at least 30mT, maybe lower). 
Then it does a leakcheck-  sneaks up at first to ~60 or 70mT, 
gives an audible alarm, then seems to shoot way up off 
scale in pressure.
