Are you certain that the performance hit is due specifically to
"req_resp_hdrs_do_reassembly()", rather than due to either

    1) the reassembly code being slow reassembling *any* large packet

or

    2) the text widget that displays the raw packet data being slow
dealing with very large amounts of text (which it *definitely* is)

or

    3) the code to build protocol trees, or the tree widget, being slow in
dealing with very large protocol trees (the code to build protocol
trees should be O(n) in the number of nodes, but the tree widget might
be O(n^2) if, for example, it appends to lists by starting at the
beginning of the list and scanning to find the end)?
