> Just realized that this test should probably not set `-Xmx128m` since we try to use 1g pages. What will happen is that the heap will be rounded up to 1G (the alignment logic here is a bit strange) so we will still test it, but it feels a bit backwards. Maybe set the heap to 1g in this case?

Good point.
