You lost me, there. Linux has filesystems like /dev, /proc, and for
your current dilemma, it has some "ramdisk" filesystems which are
careful not to not make a duplicate copy of a file when you mmap it.

So you can execute code right out of that filesystem without much
extra overhead.

If you don't want to keep a copy of the entire program in RAM (some of
it might not be executed at all or only once), then NFS mount a
remotely filesystem and run it from there.
