New submission from Raymond Hettinger:

IPython 3.0 added a useful feature that we ought to consider for inclusion either in timeit.repeat() or in the command-line interface:

"""Using %timeit prints warnings if there is at least a 4x difference in timings between the slowest and fastest runs, since this might meant that the multiple runs are not independent of one another."""
