Great idea.
I did some tests and I quickly realized that I was absolutely incorrect.
Furthermore, I don't even know what I was thinking when I posted, since
the kernel totally does the

The source code for cp is likely to just confuse anybody who needs to

You wouldn't want to use this to copy anything very big. Also, if

find the source at www.gnu.org).
