A note in case others complain of this problem.  I noticed also that this 
phenomenon occasionally happened when I played "single player" multiplayer 
games.

So it wasnt a network issue.

I opened up my case and discovered that the fan on my geForce 4 wasnt 
spinning.  I gave it a tap and now the game runs perfectly... no studders, no 
disconnections.  It simply seems to have been a cooling issue with the video 
card.
