Sigh.  I guess I wasn't clear.  The current version (1.1) of DECUS uucp (which
is what Terry is running) most definitely DOES do windowing -- that was my big 
contribution to that release [he said modestly].  The version of gnuucp which 
I started with was limited to windowsize=1, and its performance was about half 
of what Terry reports for our code.
