Why not making the BMessageRunner a bit smarter, and use a local version
whenever possible? This would not require any API changes, would cause
less use of global resources, and would make those timers much more
precise and cheaper as well.
In other words (there is no "an" before "other", stippi, btw :-)), each
BLooper would get a time based event queue similar to what stippi
proposed (just with port_count(), instead of the BMessageQueue lock).
