Doesn't that just end up calling open() and mmap()? Might not have access to the args passed through at that point, but that's going to leave a trail and of course anything interesting the mapped program does will end up going through syscalls(opening other "files").

Trying to get stuff into your memory that wasn't there before is going to require at least one syscall.
