It helps that, under Plan9, the interface to the network stack (and,
well, everything else) is defined entirely in terms of simple
filesystem operations.  Somehow, I can't see NetBSD redesigning
everything along those lines.

(let ((C call-with-current-continuation)) (apply (lambda (x y) (x y)) (map
((lambda (r) ((C C) (lambda (s) (r (lambda l (apply (s s) l))))))  (lambda
(f) (lambda (l) (if (null? l) C (lambda (k) (display (car l)) ((f (cdr l))
(C k)))))))    '((#\J #\d #\D #\v #\s) (#\e #\space #\a #\i #\newline)))))
