LazyRequestBody breaks streaming

[tarcieri]

As is, LazyRequestBody accumulates the request body as an array of strings:

https://github.com/seancribbs/webmachine-ruby/blob/master/lib/webmachine/adapters/lazy_request_body.rb#L32

This is problematic for large request bodies that we'd like to stream and process incrementally since it holds on to the entire request body in memory and thus it can never get garbage collected.

-- aside --

I've been trying to sort out streaming in Reel (especially now that we have pipelining support). This is the API I'd like to support: a socket-like one with #read and #readpartial:

celluloid/reel#75

What sort of method contract should we expect from a body supplied by a Webmachine adapter? I really like the "It's just a socket" approach.

@tarcieri Have we resolved this? LazyRequestBody no longer buffers.

Yep!
