It is totally illegal that FS calls phys-copy.

This works (INCIDENTALLY) on the Mac, ST, and AMIGA since they have
no MMU and memory protection hardware.

FS really is NOT allowed to access anything outside its address space
since it is a normal process. It has to call a kernel function to
copy stuff to another process, which might e.g. reside on another
machine!
