test_doubleOpen

public void test_doubleOpen()
                     throws InterruptedException,
                            ExecutionException

This unit test was written to track down an exception which is not always thrown for this condition. When the exception is thrown, it is thrown on the first double-open request. If the first double-open request succeeds, then the next 99 will also succeed. What we SHOULD be seeing is a nice OverlappingFileLockException, and that does get thrown a good percentage of the time.

I have since modified the test to accept the 'The handle is invalid' IOException as well. That is just making do with reality.
