The point here is not if it's simple or difficult. The point is what can
be done or not and what is faster or slower. All I'm saying is that I
don't see why it's not possible to implement the merge_segments with
only an O(1) additional cost of a few cycles per mmap syscall, which
will render the feature an obvious improvement (instead of being a
dubious improvement like in 2.2 that is walking the tree two times).
mmap does merge in many common cases.
