Crazy RAM usage when downloading

[ghost]

when downloading a 2.2 gig file and using webtorrents torrent.server() api RAM usage goes from 24mb to over 500 after a few minutes.

I'm not sure whats causing this or if a buffer can be implemented to help reduce the ram usage?

My code looks like this:

client.add(magnetURL, {
            verify: true
        }, function(torrent) {
            var server = torrent.createServer();
            server.listen(2710);
});

Found these; seems to be a known issue, and equally as crippling for webtorrents uses.

Duplicate of #248. This is high priority - will look at this soon.
