This patch was created by JP (twitter: @canoeberry) based on a memleak fix by Dirk (emacs committer) below:
https://github.com/mirrors/emacs/commit/57ae6509a3b6a274f89b9caea0284c6156470625

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

• http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

• Does the design expect failures to happen regularly and handle them gracefully?
• Have we kept things as simple as possible?
