app completly crash and server restarted sometimes

Hi @jprichardson ,
First thanks for this awesome project.
But I have a small issue with this module in Meteor. When I try to use proxy in request option sometimes for some proxy my app restarted and crash completely with following error:

W20160607-14:55:35.706(4.5)? (STDERR) events.js:72
W20160607-14:55:35.707(4.5)? (STDERR)         throw er; // Unhandled 'error' event
W20160607-14:55:35.707(4.5)? (STDERR)               ^
W20160607-14:55:35.710(4.5)? (STDERR) Error: read ECONNRESET
W20160607-14:55:35.710(4.5)? (STDERR)     at errnoException (net.js:905:11)
W20160607-14:55:35.711(4.5)? (STDERR)     at TCP.onread (net.js:559:19)
=> Exited with code: 8

This is my code:

google.requestOptions = {
            proxy: proxy,
            timeout: 3000
        };
        google.resultsPerPage = 50;

        let syncGoogle = Meteor.wrapAsync(google);

        let googleResult;
        try {
            googleResult = syncGoogle(keyword);
            for (let i = 0; i < googleResult.links.length; ++i) {
                // some process on result.
            }
        }
        catch (error) {
            console.error("error: " + error);
        }

Can you help me to fix this?

Start by tracing the requestOptions proxy path used with Meteor.wrapAsync and reproduce the logged ECONNRESET failure with a proxy. Inspect how that error is emitted and determine what behavior is expected when the proxy connection resets; done means the application no longer crashes or restarts for this case.
