```Has anyone else observed anything like the following sequence of
Timing results?

In[1]:= L = Array[Random[Integer,{-10,10}]&,{10^6,2}];
t = Table[First[Timing[Pick[L,Total@Transpose@Sign@L,-2];]/.
Second->100],{100}]

Out[2]= { 86., 89., 95.,106.,119.,132.,147.,160.,168.,179.,
190.,198.,201.,212.,219.,223.,228.,228.,232.,233.,
