I have a Server Socket that waits for connections and then creates a thread to handle them.
Once the network connection is made, I open a stream and datastream to it then wait for the remote computer
to send some data while I'm doing other things.
Is there some way (without blocking) to instantly detect that the connection has been lost if the remote computer
breaks the connection.  I've tried to use available(), but it doesn't throw an IOException if the connection is lost.
It seems a waste of valuable bandwidth to send/receive data just to check if the connection is still alive.
