Request Prioritization

[reem]

Should allow for throttling and re-prioritizing requests after they are made.

Servo notes say to talk to Patrick McManus about his work on Necko.

Considering that reads and writes for Requests require the programmer to explicitly write(msg) or read(buf), what is the actionable item here?

[reem]

I think they want the ability to prioritize new TCP connections over old ones by some form of throttling.

After an irc chat with @mcmanus, it seems the things that can be reasonably done:

1. For Http 1.x, prioritization has to be done in the client layer. If a new request comes up with a higher priority, some Rust code that's writing to other sockets need to be able to write(msg) less.
2. Http 2 introduces priorities as part of the protocol, such that the server will handle and respond to requests with a higher priority first.
