Well, rainbow does a little bit of work in order to make a new user,
then it hands over control to the activity. Since we know that activity
launching is already slow (hence the need for the module preloading
hack), it's not very surprising to me to that you see it chewing CPU
when launching activities.

Feel free to profile, though; I'd certainly like to know it if I'm doing
something truly idiotic. (Or if people are using rainbow in environments
significantly different from my own.)
