And it works here.
The old patch's failure mode, however, reveals the lack of a check for
overflowing the response ring, and that a malicious or broken domU
could (I think) put garbage into the request ring indices and cause
our dom0 to loop ~forever in interrupt context.
(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)))))
