A warning about compatibility with 4.1c/4.2:  the TCP regularly
overruns the receive window (usually by a factor of two).  This causes
extremely poor performance when the 4.2 side is sending to a non-4.2
system, as it waits for its retransmit timer to go off to resend the
out-of-window data that got dropped.
