Requests hang in Node 0.10.x

[lbeschastny]

Probably it's an issue of node.js itself, but after 5 requests amon stops sending further requests when I'm using node 0.10.x. In node 0.8.x everything works fine.

I reimplemented lib/amon.js in my branch with request to fix it.

I haven't pulled it because you renamed everything, so it's not mergeable now.

But you may be interested with my refactoring anyway, because it made amon (or is it solid now?) more stable.

By the way, do you plan to maintain amon? If you do, tt'll be great to release these changes to npm.
