In __map_request(), when adding a request to an osd client's unsent list, add it to the tail rather than the head. That way the newest entries (with the highest tid value) will be last. Maintain an osd's request list in order of increasing tid also. Finally--to be consistent--maintain an osd client's "notarget" list in that order as well.
