Stream hanging after prolonged uptime

[FOG-Yamato]

The streaming endpoint connection hangs open after a substantial amount of time (between 4 to 50 hours). This can be verified by having a tweet that passes the filters be posted and the data not being received by this connection.

Expected behavior

Stream would close or end when heartbeats no longer are coming from the Twitter API.

Actual behavior

The stream hangs with no data coming through, even possible disconnects sent by the API.

Steps to reproduce the behavior

Open a stream connection and let it work for a couple of hours or days, then verify that the connection is alive by sending a tweet that matches the filter rules.

Ideally the internal stream method would use the newlines as heartbeats to detect if they haven't been received for a period of time and closing down the stream which is not accessible to external code.
