That was on a fancy-pants Macbook Air 1.6GHz Core 2 Duo or whatever.

On one of the stock Pentium 4 2.8GHz 32-bit Linux machines in the lab, 
running Racket v5.1.1, using the same sketch-of-an-inline-cache attached 
to my previous message, I see send times drop by a factor of about 10, 
from ~260ns to ~26ns.
