Thanks Roger.

Well, the problem is: What is "whatever it takes"? The changes in this 
test are only "less bad", and typically take less time to execute. I'd 
like to keep an eye on the test after this change is pushed to see if 
there are any future issues with it.

I think, System.gc is good enough, but maybe there is scope for 
something else here.
