     Right.  I think I'll hold off a bit longer to see what other comments
people may make here before I close that port.
     BTW, I am still very interested in reading any comments people may have
regarding patterns or anything else they notice in the exit counts that I
posted here.  I looked for the most obvious stuff, but there may be other
weirder stuff going on involving port numbers that had fewer, yet still
significant numbers of, exits.
