Invalid dest causes runaway node process

Given the following code:

var express = require("express"),
    multer = require("multer"),
    app = express();

app.use(multer({dest: "h:\\drive\\does\\not\\exist"}));

I would expect an exception to be thrown stating that the destination does not exist.

Instead, the node process goes to 100% CPU and starts a runaway memory leak that very quickly locks up the system if not killed.

Opened a PR w/ mkdirp to fix this on their 0.x branch https://github.com/isaacs/node-mkdirp/pull/15

This has been resolved with the publishing of mkdirp 0.5.4 🎉
