Rainbows! is a HTTP server for sleepy Rack applications.  It is based on
Unicorn, but designed to handle applications that expect long
request/response times and/or slow clients.  For Rack applications not
heavily bound by slow external network dependencies, consider Unicorn
instead as it simpler and easier to debug.

The major feature of this release is the new DeferredResponse
middleware for the Rev-based concurrency model.  It should be
transparently compatible with non-Rev models, as well.  As a
pleasant side effect, this change also allows large files to be
streamed to the client with Rev as the socket becomes writable
instead of slurping the entire file into an IO::Buffer first.

Bugfixes to graceful shutdowns support for all concurrency
models.  The Rev-based model also gets a working heartbeat
mechanism (oops!) and fixed HTTP/1.1 pipelining support.
