RFR of JDK-8188897: java/rmi/registry/reexport/Reexport.java failed with Port already in use

[Roger Riggs]

Hi Hamlin,

Instead of a simple time delay, it would be useful to wait for the 
RegistryVM to terminate.
In killRegistry: 149,  adding subreg.waitFor() should be sufficient.

58: If using a 'for' loop it would be easier to understand if it 
included the usual start, increment and termination.
Instead of burying it in the exception handler.

59, 102, 104: the introduction of the kill boolean makes the test harder 
to understand and seems to be unnecessary.
  the killRegistry() method already will only kill the subprocess if it 
still is alive.
