Performance 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.
