Performace patch for ruby-1.9.3-p327

Changes:

  • this version includes backport of Greg Price's patch for speedup startup http://bugs.ruby-lang.org/issues/7158 .

    ruby-core prefers his way to do thing, so that I abandon cached-lp and sorted-lf patches of mine.

  • this version integrates 'array as queue' patch, which improves performance when push/shift pattern is heavily used on Array.

    This patch is accepted into trunk for Ruby 2.0 and last possible bug is found by Yui Naruse. It is used in production* for a couple of months without issues even with this bug.

Neocities' Rainbows! config file - https://neocities.org
# This is Neocities' Rainbows! config file. We are using this in production to run all our web apps.
# It works really well for us and has been heavily load tested, so I wanted to share it with the community.
#
# In my opinion, this is the best way to deploy a ruby web application. Unlike EventMachine based solutions,
# it uses real ruby threads, which allows it to take advantage of the internal non-blocking IO pattern
# in MRI.
#
# Contrary to popular belief, MRI doesn't block execution to wait on IO when you are using threads, even
# with the GIL. The requests are done concurrently for anything that is based on the IO class. This
# includes things like Net::HTTP and even `system commands`. Grep the MRI Ruby source code for
