That's... seriously weird.  Even if the TCP is somehow not working
correctly, SSH has its own cryptographic integrity/authenticity check
on top of that, so characters _really_ shouldn't be getting silently
dropped there.  Maybe the loss is in the tty layer?

(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)))))
