But then the concurrent users interfere with each others'
computations, don't they? If a user is lucky enough to hit the server
with a request when nobody else does, he'll get to utilize more memory
(and potentially arrive at a different answer) than if he hits the
server when 10 other people do, and have all of their computations
compete for memory. That does sound like an unfortunate trait in a
webapp.
