Follow-ups
--- Bernd Schmidt 2009-06-17 09:55:37
Ehhh.
Look at the min/max numbers. It seems the clock isn't accurate enough to test
what you're trying to test, it seems to have a resolution of 4ms (which
translates to a HZ of 250), and all the calls to malloc are faster than that.
Besides, MPU obviously has more overhead than no-MPU. A few CPLB faults at the
wrong time could easily make this test fail.
Closing this as not-a-bug until proven otherwise.
