    statsd = TCPStatsClient(host='1.2.3.4', port=8126, timeout=1.)

The :py:class:`TCPStatsClient` class has a very similar interface to
:py:class:`StatsClient`, but internally it uses TCP connections instead of UDP.
These are the main differences when using ``TCPStatsClient`` compared to
``StatsClient``:

* The constructor supports a ``timeout`` parameter to set a timeout on all
  socket actions.

* :py:meth:`connect() <TCPStatsClient.connect()>` and all methods that send
  data can potentially raise socket exceptions.

* **It is not thread-safe**, so it is recommended to not share it across
  threads unless a lot of attention is paid to make sure that no two threads
  ever use it at once.
