This is an overflow problem in the way the mean is computed I believe --
it would start to add nothing after a while. In any case you can get the
correct/better result with b.mean(dtype='float64').
Maybe someone else can give some more info on why. Just to throw it in,
maybe a warning could be issued by checking something using
log2(size*mean) and float precision?
