[PATCH] DefaultSocketImplFactory

[Christopher Hegarty - Sun Microsystem]

Hi Roman,

This is clearly legacy code but I can see that DatagramSocket has such a 
property. I don't see any problem adding a property, I suppose I just 
question it's usefulness. If it is something that you think we really be 
useful then maybe you could flesh out the implementation (including 
ServerSocket) and a simple test.

-Chris.
