RFR 6791551: ExclusiveBind.java has a race condition

Jaroslav,

Your fix should work in most case, but is it better and more reliable to 
wait a VM event as suggested in the bug? even your timeout is adapted to 
the test time factory, but the solution still depends to a fixed timeout 
and a  fixed line out.
