I'd like some people here that have slow machines to try it and report whether it is fast enough to be usable for them. A large number of overlays is slowing down every operation in the buffer. Having a set of 50 or so that is only adjusted upon redraw should be the fastest option for that reason. If the overlay creation is time-critical, one might move keep some off-screen overlays in a separate list for reuse and detach them from the buffer temporarily. Those sound like improvements.
