If image responds after timeout then the node process crashes

[struan]

The server falls over with a stack trace:

http.js:689
    throw new Error('Can\'t set headers after they are sent.');
    ^
Error: Can't set headers after they are sent.

And pointing the proxy at the image served by this example node app should replicate the error:
