Subject: Evict timed out pooled socket periodically

Previously we only scanned pool socket to check they are timed out
when we pooled another socket.  This means that pooled socket is not
closed long time (stays in CLOSE-WAIT state) if we don't pool any more
socket.  In this commit, we now check pooled socket periodically (30
seconds) to avoid the sockets hanging in CLOSE-WAIT state long time.

See GH-477
