Rsync doesn't call sqrt -- it just does a simple little integer
estimation. It is probable that using a hardware sqrt call would be
faster than rsync's estimator, but taking only 0.00000041 seconds per
file instead of 0.00000232 seconds per file(*) is not going to make
much difference, even with a really large number of really large files.
* Actual measured values for taking the sqrt of 837,293,847,384 on a
fairly slow VIA processor. Note that the estimator gets faster on
