Well, people do sometimes speak of "hot" pages (or spots) ... and there
are no good verbs associated with "activation count". Oh, and you might
say "the situation heats up" in case of increasing memory pressure.

And remember that in physics, temperature (at least in the cases where
it's used by non-physicists) does measure something approximately like
average particle velocity, which some (non-physicist) people might well
call "activity".
