[e2e] Windows XP TCP Behaviour

I have recently been doing some testing of TCP implementations on an
isolated network we have available in our research group. I've noticed
some odd behaviour from Windows XP Service Pack 2 and was wondering if
anybody else had encountered such weirdness and whether it affects other
versions of Windows.
I've described the most notable problem at:
What we see here is that Windows is sending data outside of the
receivers advertised window!
I've also noticed Windows sending weird sized packets in what is
supposed to be a simple bulk data transfer (often sending packets with a
lot less than an MSS worth of data).
Note that the situation described in that link is very simple; just two
machines connected over an otherwise unused bottleneck link.
