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

• rbenv
• ruby-build

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.

/*
Parallel processing with ordered output in Go
(you can use this pattern by importing https://github.com/MarianoGappa/parseq)

This example implementation is useful when the following 3 conditions are true:
1) the rate of input is higher than the rate of output on the system (i.e. it queues up)
2) the processing of input can be parallelised, and overall throughput increases by doing so
3) the order of output of the system needs to respect order of input

- if 1 is false, KISS!

First, add pry-rails to your Gemfile:
https://github.com/rweng/pry-rails

gem 'pry-rails', group: :development

Then you'll want to rebuild your Docker container to install the gems
