I don't think undump is a hack except to the extent the whole thing is a hack. Linux shoves a lot of stuff to userspace that other operating systems put in kernel space; this is just another one of them.

The program loader is not magic - it just reads a list of things to mmap and then mmaps them. If you write a thing that writes a list of what's mmapped and call it the unloader... fine?
