Problem Text Test may fail on implementations with large itimer granularity. The exec*() 1 tests fail on our IUT because they think the interval timers are not properly preserved across the exec*() calls. However, the tests are rely on a finer granularity than our IUT supports, and according to CASPEC (on the getitimer page), the value may be rounded up to the next supported value. Specifically, the test is requesting a it_interval.tv_usec value of 89 and reading back a value of 10000.
