The attached (highly experimental) patch seems to improve the

the factor of six-through-ten I was seeing earlier is, I speculate,
related to object-ref taking a lot of time.
Interestingly, the performance of (send something message) is, with this
patch, seemingly roughly en par with the performance of generics
captured using generic and invoked using send-generic.
I haven't yet tried running a full racket system with this patch
applied. I wonder if it makes a difference to the interactive
performance of DrRacket?
Robby: What happened to the drracket automated gui tests? I remember
there used to be an environment variable to enable the button that ran
them, but I can't find it in the manual or in the source tree.
