What seems to be happening is that every time a packet is lost, NT doubles
its timeout period -- regardless of the actual round-trip time for the link.
After 4 or 5 packets have been lost, NT's timeout has jumped up to several
seconds even though 90+ percent of the packets are ACK'ed within 10-20ms.

Unix hosts, OTOH, seem to actually keep track of the round-trip time for the
link, and calculate a more useful time-out period based on that.  Either
that or they just guess better than NT does.
