Closed Issue: node-gyp doesn't work in Interactive window [1735]

Note: Experienced on Windows 7

Installing a binary package with `.npm install` in the Interactive window fails because node-gyp complains about stdin. Here's the full log:

```

It looks like there's something funky about the way we redirect process output that causes this.
