You're looking in the wrong place. It's unstable because of
infrastructure problems which require fairly substantial amounts of
work to correct.

I guess that is what I am asking... What is different between the following:

int foo(void){
return 0;
}

and

int foo_prime(void) {
return foo();
}

That is my interpretation of the code.  It would *seem* to just pass the 
call off to the next FS layer as if the VFS system of the kernel had done it
directly Conceptually I must be missing something.

Umm, umapfs rewrites the owner/group of vnodes if I'm not mistaken.
That's the whole point with it.
