In build 303, about 75 MB was consumed before an activity
even got a chance. That left about 53 MB for the activity.

I notice that the non-activity stuff isn't done yet. I hope we can
keep the currently available RAM for activities. Burning RAM on the
other stuff feels very wrong to me; the other stuff is only there
to support the activities.
