Subject: fileutils: speeding up cp.

> I've noticed that the mv command preextends the file so that all
> required bytes are preallocated.  This happens even when the mv
> must cp the file from one drive to another.  This doesn't happen with
> itself.  I'm trying to find where in the source this happens so that I
> can supply a patch that'll cause cp to preallocate the space always.

> If you wish to test the behavior yourself, then use the floppy drive
> because of it's slowness.
