Exactly right Bob.  The 10811 guys used to go nuts
about keeping water out of their vacuum system.
There were certain temperatures known as "water
points" at which some water was released.
The retained water was in spite of the temperature
already being above 100 degrees C (boiling).
It has something to do with monolayers of
water molecules not boiling away.
