This paper describes the very early work that led to TOPP.  The work
exhibits some deficiencies that we did not know the cause of at the
time of writing; one cause being the Ethernet capture effect.  Please
see Bob Melander and Mats Björkman's later work on TOPP for better and
more complete results.
