Can't remember exactly, I think it was bad enough for a test case
which seemed pretty realistic so I discarded that option.
Basically what I remember is that I got the impression that it would
probably harm more users than the problem at hand.

PS: BTW, the number of markers is not the only issue: the order in which
they are created also matters.  Maybe we should try Sebastian's test
case but creating the markers/overlays in random order (and if that
helps, we could get a similar effect by making the GC randomly shuffle
the buffers's list of markers ;-).
