At first it looks fast, but it seems to block more. When going from a
large dir to another and back again, the old flikkering behaviour
re-appears and it blocks for a while. Small dirs, due to blocking, seems
to be slower with this patch.
(All measure done with a wet finger in the wind)

Note, I have a slow box, K6II-300.
