Just a quick update on this effort. Michael has changed the SOCKS and 
HTTP proxy SocketImpl implementations to use delegation rather than 
sub-classing so they can delegate to the new NIO based SocketImpl or the 
old PlainSocketImpl. We've added a system property so you can run with 
-Djdk.net.usePlainSocketImpl or -Djdk.net.usePlainSocketImpl=true to use 
the old implementation. Existing tests are passing with both the old and 
new implementations so I think this effort is starting to look good. I 
expect we will be at the point soon where we could use some help from 
those with libraries or applications that use the old 
Socket/ServerSocket APIs extensively.
