There are also alternate cooldown strategies that might help newfs-like
access patterns and wouldn't harm sequential writes, but I don't know
how they'd do with the many-small-files cases. This might be worth
experimenting with, now that I think about it.
(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)))))
