preventing sleep during compilation

Check out Caffeine at the Mac app store.  It drops something in your toolbar
at the top of your screen (looks like a coffee mug).  A single click and it
prevents your computer from going to sleep and/or showing the screen saver.
(Easiest manual way of turning sleep on/off I've seen)

I've never had my MacBook Pro turn off, either (I don't have a desktop to
try it out on), but the hardware is different.  It could be that your HDD
cache is bigger/better on the iMac so it doesn't have to spin up as often
(indeed, maybe not even often enough to register before going to sleep).

Does it actually go to sleep mid-compile?  Or does it get stuck somewhere
(i.e. in download stage) where computer resources aren't used so it assumes
all is safe to sleep?

Hope some of that helped,

(I always forget to reply to all!)
