Yeah, okay, looks like this works:

#lang racket

(require ffi/unsafe)

;; return type is "gid_t". Safe to use int?
(define setuid
  (get-ffi-obj "setuid" (ffi-lib #f)
               (_fun _int -> _int)))

(setuid 0)

... naturally, the setuid 0 fails, you'd have to start as root and go down. Also, you'd need to do that *after* the listen on port 80.
