Subject: [ANN] Rainbows! 4.0.0 - Unicorn for sleepy apps and slow clients

MOAR concurrency for MOAR COARS!

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.

* http://rainbows.rubyforge.org/
* rainbows-talk@rubyforge.org
* git://bogomips.org/rainbows.git

Changes:

Rainbows! now scales to more than 1024 worker processes without
special privileges.  To enable this, Rainbows! now depends on
Unicorn 4.x and thus raindrops[1].

client_max_header_size directive is added to limit per-client
memory usage in headers.

An experimental StreamResponseEpoll concurrency option now
exists to buffer outgoing responses without any thread-safe
dependencies.  Unlike the rest of Rainbows! which works fine
without nginx, this concurrency option is /only/ supported
behind nginx, even more strongly so than Unicorn itself.
non-nginx LAN clients are NOT supported for this.  This relies
on the sleepy_penguin[2] RubyGem (and Linux).

There are some minor bug fixes and cleanups all around.  See
"git log v3.4.0.." for details.
