Okay with me.. I tracked down the November thread on net-dev where this 
came up but I couldn't find anything that fully explained it.

I think this looks good.

Just a few minor comments on the Scoping.java test
- both DatagramChannel and DatagramSocket implement AutoCloseable so the 
test can using try-with-resources.
- I suspect socketTest leaks a connection as it establishes a connection 
but doesn't accept/close it. Probably not a concern as the test is /othervm.
I don't need another webrev on those points.
