* This runs the parts of the gtest which make sense in large-page scenarios
* (mainly os*).
* Note that if these tests run on a system whose kernel supports large pages
* but where no huge pages are configured, these tests are still useful. They
* will test correct initialization. Later reserve calls will fail and fall
* back to small pages (while complaining loudly) but this should not affect
* the gtests.
