v0.7.0

Rainbows! 0.7.0

keepalive_timeout (default: 2 seconds) is now supported to
disconnect idle connections.  Several new concurrency models
added include: NeverBlock, FiberSpawn and FiberPool; all of
which have only been lightly tested.  RevThreadSpawn loses
streaming input support to become simpler and faster for the
general cases.  AppPool middleware is now compatible with all
Fiber-based models including Revactor and NeverBlock.

A new document gives a summary of all the options we give you:

If you're using any of the Rev-based concurrency models, the
latest iobuffer (0.1.3) gem will improve performance.  Also,
RevThreadSpawn should become usable under MRI 1.8 with the next
release of Rev (0.3.2).
