Minor nit. Please change both:

Thread.currentThread().sleep(10);

to

Thread.sleep(10);

sleep() always applies to the current thread.

Also, as it is a boolean variable style dictates that:

while (Running.running != true) {

be written as:

while (!Running.running) {

One related query with this test: are we guaranteed that the loop of 
System.gc() calls will trigger class unloading?

Thanks,
David
