Stream close is not working

[axfree]

This simple test code hangs the process forever.

// pb.js
var PushBullet = require('pushbullet');

var pusher = new PushBullet(‘…’);

var stream = pusher.stream();
stream.on('connect', function() {
    console.log('connected');
    stream.close();
});
stream.on('close', function() {
    console.log('closed');
});
stream.connect();

$ node pb.js
connected
<< process hangs here >>
