Since all the code is extremely public can I make a strong request that

preferable.
I'm willing to fix all the code (assuming its in svn/git somewhere) if no
one feels like updating the examples.
With 7 lines and about 40-some characters per line, it's really hard
to write code that reads like a novel. Short variable names are a
tool of the trade. Heck, the little blurb that the "?" link opens has
more room to explain what the variables are for than the code itself
does.

#lang racket
(define listener (tcp-listen 12345))
(let echo-server ()
(define-values (i o) (tcp-accept listener))
(thread (lambda () (copy-port i o)
(close-output-port o)))
(echo-server))
I count 11 unique "novel"-esque variables in that example, and only 2
"tools of the trade" variables. I think this is a reasonable mapping to
go from short to long:
o -> out
i -> in
