Rainbows!

This release fixes two EventMachine bugs.

This release adds a bugfix to allow stream(:keep_open) in Sinatra (and possibly other async.callback users) to work properly with EventMachine. There are no changes for non-EventMachine users.

This release adds one bugfix for users of Fiber-based concurrency options.

For epoll/Cool.io-based concurrency models, shutdown() is now used to timeout keepalive clients to avoid race conditions. Minor documentation improvements were made.

This release fixes a potential reentrancy deadlock when
using the default logger from the Ruby standard library.
