 Regarding (2), I'm no longer so sure we should change the weight of the
 CPU. Using 100% of processor time is definitely an improper thing to do
 for an activity. It slows down the machine and draws a lot more power.
 Therefore, should reflect this problem in the frame icon. On the XO-1.5,
 and other machines with plenty of memory, 100% of CPU is already not
 sufficient by itself to make our tamagochi cry. If it's enough on the
 XO-1, it's only because the overall situation is *really* much worse.

 I would give a try to (3) to see if it's really viable. It works well for

 That said, I'd encourage everyone not to aim at getting this code perfect
 before allowing it in. A patch that improving the current situation is
 already a big step forward. Heuristics can always be refined and improved
 by later patches, possibly submitted by those who are unhappy with the
 behavior on their particular platform.

 As Jim Gettys would say, perfect is the enemy of good.
