This one wasn't when I was there.  I think we also had a oil 
spraying event there, but it was relatively contained.  We 
had one at Washington University, also that might have 
contaminated several spindles before they got all the packs 
I think this one is fairly quickly detected if the computer 
room is occupied, it causes a strong oily smell that is 
quickly spread by the A/C system.
