RFR : 8016728: TEST_BUG: test/java/rmi/transport/closeServerSocket/CloseServerSocket.java failing intermittently with "Address already in use"

[Seán Coffey]

Hope this is a simple one. This issue is a rare intermittent one :
> - port 48250 is free
> - exported registry: RegistryImpl[UnicastServerRef [liveRef: 
> [endpoint:[10.169.79.100:48250](local),objID:[0:0:0, 0]]]]
> - port 48250 is in use
> - unexported registry
> java.net.BindException: Address already in use
> at java.net.PlainSocketImpl.socketBind(Native Method)

Even though we've just unexported the registry, the socket is still in 
use. I believe 1ms is too short a time to sleep to handle any 
environment issues. Let's try 1 second.
