= TODO items for Rainbows!

We're lazy and pick the easy items to do first, then the ones people
care about.

* Improve test suite coverage.  We won't waste cycles with puny
  unit tests, only integration tests that exercise externally
  visible parts.

* Rev + Thread - current Rev model with threading, which will give
  us a streaming (but rewindable) "rack.input".

* EventMachine.spawn - should be like Revactor, maybe?

* Rev + callcc - current Rev model with callcc (should work with MBARI)

* Fiber support - Revactor already uses these with Ruby 1.9, also not
  sure how TeeInput can be done with this.

* Omnibus - haven't looked into it, probably like Revactor with 1.8?

* Packet - pure Ruby, EventMachine-like library

* Rubinius Actors - should be like Revactor and easily doable once
  Rubinius gets more mature.

* test and improve performance (throughput/latency/memory usage)
