Rainbows! 4.1.0 - Unicorn for sleepy apps and slow clients

Rainbows! is an HTTP server for sleepy Rack applications. It is based
Unicorn, but designed to handle applications that expect long
request/response times and/or slow clients.

Changes: (minor internal cleanups)

There are only some minor cleanups in this release and a bump to
kgio 2.5 to remove the dependency on io/wait. kgio 2.5 or later
is now required (kgio 2.6+ will be required in the next

I don’t recall hearing of anybody running Rainbows! in production
and serving public traffic, yet. You can be the first! Have fun!
