Demo for NodeJS preemption bugs via node::MakeCallback.

Usage:

• node 0.12.0 should be on your PATH
• grab all the files from this gist into the same directory
• node-gyp rebuild to compile preemptor.cc into build/Release/preemptor.node
• node demo to run the demo

For me, the demo output is

1. Check out node 0.10.33 source
2. ./configure --without-snapshot --debug
3. make
4. copy/symlink out/Debug/node so it's the node binary on your path
5. create a package.json with the following contents

{
  "dependencies": {
    "archiver": "0.13",

If you build Node.js from source and want to try both the Debug and Relase configurations, and you notice that if you do

% ./configure --without-snapshot --debug
% make

you get both Debug and Release versions, and you think you can use them normally, think again:

require('webkit-devtools-agent')
b1 = fs.readFileSync('/usr/bin/nodejs')
b2 = fs.readFileSync('/usr/bin/nodejs')
c1 = b1.toString(); 0
c2 = b2.toString(); 0
c1 === c2 // true!
