 At WordCamp San Francisco 2011 (WCSF2011) we discussed optimizing
 wp::parse_request by converting the flat array of rewrite_rules into a
 tree by inspecting common prefixes. The proof-of-concept code performed on
 average about 1ms faster per parse_request. Core team decided to shelve
 the idea as the added complexity is hard to justify with a 1-2% speed
 improvement.

 The attached patch is a snapshot of the code as it stood on my
 wordpress.com sandbox during speed testing. The script treetest.php was
 run from wpsh.
