Looking for a sponsor to review changes made to two unit tests under jdk/test

Mani,

Please go back to my original response. As Alan has just re-stated we do 
not need a latch or a semaphore here because we already do a join on the 
thread. As I have said the sleep is to allow the GC a chance to run (eg 
finalizer and/or reference processor thread).
