This should fix ethereum#27726. With enough load, it might happen that the SetPongHandler callback gets invoked before the call to SetReadDeadline is made in pingLoop. When this occurs, the socket will end up with a 30s read deadline even though it got the pong, which will lead to a timeout. The fix here is processing the pong on pingLoop, synchronizing with the code that sends the ping.
