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)
})
}
``
