Ok here is a W-I-P. One test case is not cleaning up properly. You may note that I
still give some room for gc not to unmap immediately, but at the end of the program
we hope that will be the case and I think the missing case is just a bug and not GC
being delayed. The counter testcount is only here for debugging this problem.
