    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.
