rewire() doesn't detect when source file tries to rewire itself - stack overflow

[jghaines]

self-reference.js var rewire = require('rewire'); var lib = rewire('./self-reference.js');

When run (mocha 2.4.5, node v4.3.0) $ mocha ./self-reference.js

Expected Error: file "./self-reference.js" tries to rewire itself (self-reference.js:2)

Actual It crashes with "Maximum call stack size exceeded" - full trace below

Yes, this is user error. I managed to do this with insufficiently deep parent-directory-ing ../../../../lib/module/sub-module/source.js
