How does one normally handle this? I would think it might be best to cycle 
through (say) three sets of nearby AI, evaluating a third of the AIs and 
taking up the whole amount of time. It's not like real humans don't have a 
60ms delay in their reaction times. :-)

I've been amused when I noticed (for example) that the AIs in the older 
thief games keep moving when they're far away, but they stop walking. As in, 
they'll just skate back and forth until you get close. There's only a couple 
places in the game with line of sight straight enough to see it, tho.

And in bioshock, it's not unusual to hack a turret, walk away, come back 20 
minutes later, and find a big pile of bodies and a half-broken turret, 
indicating that the game at least *seems* to keep running all the AIs and 
spawning enemies even in areas where you aren't.
