Indeed.  Of the many postings on this thread, Bob H's strikes me as 
pointing up the most salient point:

         Do not use simple rules for turning off a TCP mechanism.

(For most situations, that reduces to the simple rule:  do not turn off TCP 
mechanisms.)

It was frankly a bad idea to play local/distant games 20 years ago and 
things have only gotten worse.
