Rainbows! is an 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.

Changes:

This release contains minor bugfixes/compatibility improvements
for ThreadSpawn, ThreadPool and EventMachine users.

Excessive error messages from spurious wakeups using
ThreadSpawn/ThreadPool under most platforms are silenced.  Only
Ruby 1.9 users under Linux were unaffected by this bug.

EventMachine users may now use EM::Deferrable objects in
responses, vastly improving compatibility with existing
async_sinatra apps.
