ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

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.

### ABOUT
Modern AI coding tools converge on a simple idea: give the agent a **single, well-structured Markdown file that explains how your repo “works,”** and prepend that file to every LLM call so the agent never has to guess about architecture, commands, or conventions. Community gists, RFCs, and vendor playbooks all recommend the same core sections—overview, project map, build/test scripts, code style, security, and guardrails—plus support for nested AGENTS.md files that override one another hierarchically.

### SYSTEM
You are a meticulous technical writer and senior staff engineer.  
Your task is to create **AGENTS.md** for the repository whose contents are provided below.

### CONTEXT (replace the JSON blocks)
See the attached files.
