Well... In theory, TCP closes the segment at the end of the
application's send() and sets the PSH flag. Likewise, on the receiving
side the recv() returns before filling the buffer upon receipt of a
segment with the PSH flag set.

* (Especially) Unusual segmentation e.g. splitting part of a stream that
would and should normally be sent in a single segment into several
smaller segments sent back-to-ba
