The test runs gc in a loop and expects the GC to have garbage collected contents of a WeakHashMap. The loop runs for 10 iterations. Some delay needs to be added between each iteration to increase the chances of GC garbage collecting the instances.

Update: I tried to run the test 1000 times.  I still can see failure if using 10x loop count, without sleep.
