While it it true that Windows NT and Windows 2000 both implement
Fast Retransmit, in many cases, due to a bug in the implementation,
Fast Retransmit is never invoked, and the TCP sender has to wait
for a Retransmit Timeout to retransmit a lost packet. This is
discussed in more detail in the TBIT paper by Padhye and Floyd,
available from "http://www.aciri.org/tbit/".
