i think that's incorrect: it ensures a push of any data that is already buffered but un-pushed
(ie, the immediately preceding segment had no PSH, and the receiver's implementation buffers
accordingly).

part of the problem with the continued specification of protocols, even 30 years on,
as `formal' english text is that it can appear to be ambiguous when it's just subtly precise.
that's why i had to say `i think' as opposed to QED
