Shall fcp on Linux use `posix_fadvise(POSIX_FADV_NOREUSE)`?

A significantly faster alternative to the classic Unix cp(1) command, copying large files and directories in a fraction of the time.

Also there may be option to set POSIX_FADV_DONTNEED for target files, so that they don't dangle in filesystem cache unnecessarily.

At first glance this seems like a good idea, I'll look into it further if I have the time.
