1. Add a common code cache. Save parsed js libraries locally; also other resources.
Detail: Chrome should detect common subresource requests and satisfy them with local copies. This puts (good) pressure on devs to
*stop bundling code*. I'd like to see a special page in chrome (e.g. chrome://codecache) that lists out all the
subresources I currently have. Ideally, the JS resources would be stored in a clonable pre-parsed state, and optionally
make them immutable. The same could be applied to CSS, images, and fonts. Over time my Chrome instance would accrete a
list of resources, and get faster and faster. Combine with subresource integrity, or implement more losely (does it really
matter what version of jQuery this site needs? Probably not.) Another nice feature of this is we'd be able to use the
unminified code without a performance hit improving idea- and technique-sharing. The tradeoff is risk of breakage.
This can be prototyped with a browser extension.

1 Let's try something different. The left child goes to the right.

2 3 <--- No room for 3.left 1 2 4 7
/ \ \ 3 9
4 5 6 5 <-- The oddness is here because we had to skip a row.
/ \ 6 But there is no ambiguity!
7 8 <--- Width totally determined by leaves! 8
