This is a general purpose S3 upload/download library using EM::Deferrables which can retry while accessing from S3. Who doesn't want to retry when they get a 5xx from S3?

A serialization framework on top of S3Interface which could possibly occur when you are putting objects in S3 in a reactor loop. Crude but works.

• Doesn't (yet) run the event loop. I developed this when I was working on a Thin based app server. Future versions may have support for running an event loop.
• Works only for get_object and put_object. More methods coming soon.
• Do not define errbacks on instances of S3Interface. It uses errbacks to retry and always succeeds and responds with an error code in case of an error.
• Feel free to fork and modify.
