dezalgo

Contain async insanity so that the dark pony lord doesn't eat souls

See this blog post.

USAGE

Pass a callback to dezalgo and it will ensure that it is always called in a future tick, and never in this tick.

```javascript var dz = require('dezalgo')

var cache = {} function maybeSync(arg, cb) { cb = dz(cb)

// this will actually defer to nextTick if (cache[arg]) cb(null, cache[arg])

fs.readFile(arg, function (er, data) { // since this is already defered, it will call immediately if (er) cb(er) cb(null, cache[arg] = data) }) } ```
