This was added to workaround for red5 taking a while to rewrite the
serialized (.ser) data that it streams to disk back to the .flv format.

The workaround is no longer needed, for two reasons:
* The sanity scripts run the red5 code to generate the .flv from the .ser
  if needed, and
* We're expecting more people to be using WebRTC media in the future anyways

This makes recordings available up to 2 minutes earlier than they would have
been otherwise.
