A replacement for process.exit that ensures stdio are fully drained before exiting.
npm install exitA replacement for process.exit that ensures stdio are fully drained before exiting.
To make a long story short, if process.exit is called on Windows, script output is often truncated when pipe-redirecting stdout or stderr. This module attempts to work around this issue by waiting until those streams have been completely drained before actually calling process.exit.
See Node.js issue #3584 for further reference.
Tested in OS X 10.8, Windows 7 on Node.js 0.8.25 and 0.10.18.
Based on some code by @vladikoff.
npm install exit``javascript
var exit = require('exit');
// These lines should appear in the output, EVEN ON WINDOWS.
console.log("foo");
console.error("bar");
// process.exit(5);
exit(5);
// These lines shouldn't appear in the output.
console.log("foo");
console.error("bar");

In Windows, clone the repo and cd to the test\fixtures directory. The only difference between log.js and log-broken.js is that the former uses exit while the latter calls process.exit directly.
