I just rebooted both machines and it didn't fix the problem. I did a
packet trace on both boxes and there does indeed appear to be packet loss.
I may have thrown out a red herring, sorry about that folks! Something
odd is going on, that's for sure. My packet trace shows that there was
packet loss and that the retry did *NOT* occur immediately, so my
premise goes out the window.
I don't understand why my tcp connection has this sort of packet loss when
all of my ping tests succeed 100%. I am totally baffled.

(make window wide to view. Note: my xntpd's aren't synchronized well
enough this soon after reboot so the two machine's times do not match
very well).
