Request for review: 8009650 - HttpClient available() check throws SocketException when connection has been closed

[Rob McKenna]

Hi folks,

This is a slight alteration of the fix contributed by Stuart Douglas. 
This fix deals with a SocketException caused by getSoTimeout() on a 
closed connection.
