> don't you just want rfork Nm?

I don't think so, that is worse, this would really mean
I couldn't mount anything.

I don't mind the new app adding mounts if it wants to, but
I want it to start with a new root dir and children, so
I need to flush out the old namespace.

the problem is as soon as I do that I lost contact with the
mount command and as its not a shell builtin this means I
can never get back the namespace I have lost.

I am stuck in no-mans-land.

its easy enough to experiment:
	open a window
	type rfork N
	try to get ls to work.

I can pass an open file descriptor across
the rfork N boundry, but I still cannot mount it.

The only solution I can see is to write some C code, but
I was hoping somone might see a trick I missed.
