A word of warning to those who were planning on using wbdiff this
weekend - the temperature settings for both hot pots has been set to
60C, and, as far as I can tell, can't be changed back to their normal
settings by regular users. 60 degree piranha is obviously not sufficient
to clean wafers, so until this problem is fixed I think the only way to
do a diff clean is to change the chemicals and allow them to self heat.
But the hot pot maximum drain temperature has also been changed to 50C.
I accidentally turned on the heater first, and after waiting a full hour
the temperature had only dropped from 60C to 55C so I gave up and went home.
