It's not a bug in the library -- your machine is too fast.  The test is, as 
much as anything, a test that the clock on the machine provides monotonically 
increasing values.  So there's 3 possible solutions.  1) Change the test to 
use >= in the time comparisons, 2) increase the number of loops between 
measurements, or 3) ignore it.
