    66 * Default (digits=0) case of around is 10x slower than {{{(x+0.5).astype(int).astype(float)}}}. Resolved: changeset:2151 implements fast rint function and adds a round method to ndarray that is about as fast for digits=0 case. 
    77  
    8  * As of changeset:2173 {{{x.fill(1)}}} is 2x slower than {{{x += 1}}}.  One should be able to set memory to a constant value faster than autoincrement. [wiki:PossibleOptimizationAreas/FillDiscussion Discussion]. 
     8 * As of changeset:2173 {{{x.fill(1)}}} is 2x slower than {{{x += 1}}}.  One should be able to set memory to a constant value faster than autoincrement. [wiki:PossibleOptimizationAreas/FillDiscussion Discussion].  Implemented in changeset:2188.
