------- Additional Comments from Tim Horton <timothy_horton at apple.com>
I'm still not sure we want to take this approach, but the log channel approach
seems like a dead end. Ideally, we'd be able to hand structured data to
clients, but I haven't had a chance to look into how to make that work yet, and
it seems likely that that approach will involve equal or greater amounts of
plumbing.

In either case, we will still need to keep the "reason" for dropping to
main-thread scrolling around, which this patch does.
