Imagine something like:

      ;

    var options = {
      ignoreCookies: true,
      cacheStatics: 300 // 5 minutes, unless an explicit cache-control header is given
    };

;; This was damn hard.
;; 
;; One of the exercises near the end of The Little Schemer requires defining
;; a function that uses a collector to remove odd numbers, recursively from
;; a list, sum the odd numbers and multiple the even numbers.
;;
;; This is it.
;;
;; It requires currying lambdas one inside another to deal with the recursion
;; in the collector function.

# Instructions for use
#
# 1. Execute "time rails runner nil" a few times in your shell, see how long rails takes to boot
# 2. Add this monkey patch to the top of config/boot.rb
# 3. Repeat step 1.  What's the difference?
#
# This is just an experiment, but it gains me 30% on Rails' start time, which suggests there is something
# in Rails that is breaking the "run only once" behaviour of #require.
#
# Note: You can't override Kernel#require, since Rails by-passes it most of the time.
