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.

This release fixes a memory leak in our existing Revactor  
concurrency model. A new RevThreadPool concurrency model has  
been added as well as small cleaups to exit handling in workers.
