* Add faster and simpler http.parser (maybe, based on h11 [1]) and avoid
using email module in http module.
It's always risky making predictions, but hopefully by the time 3.8 is out, requests will have switched to using h11 directly instead of the http module. (Kenneth wants the big headline feature for the next major requests release to be async support, and that pretty much requires switching to something like h11.)
I don't know how fast importing h11 is though... It does currently compile a bunch of regexps at import time :-).
