Switch from using String#match to using String#=~. There's no need to

class_attribute gets instance methods which delegate to but may override their class values as you'd expect. Disable instance writer methods with :instance_writer => false.

add lazy_load_hooks.rb, which allows us to declare code that
should be run at some later time. For instance, this allows
us to defer requiring ActiveRecord::Base at boot time purely
to apply configuration. Instead, we register a hook that should
apply configuration once ActiveRecord::Base is loaded.

With these changes, brings down total boot time of a
new app to 300ms in production and 400ms in dev.
