The point here is not if it's simple or difficult. The point is what can

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.
