* Use commit limit to test exhaustion instead of trying to exhaust virtual memory. * Use exact roots where possible so that we don't have to worry about local variables pinning down memory. * Reduce sizes and iterations so that tests complete in a reasonable amount of time. * Use "MVT" instead of "MV2". Update the list of passing test cases. Copied from Perforce Change: 186035 ServerID: perforce.ravenbrook.com
