This patch reduces the running time for hmm-tests from about 10+ seconds, to just under 1.0 second, for an approximately 10x speedup. That brings it in line with most of the other tests in selftests/vm, which mostly run in < 1 sec. This is done with a one-line change that simply reduces the number of iterations of several tests, from 256, to 10. Thanks to Ralph Campbell for suggesting changing NTIMES as a way to get the speedup.
