This is why filename completion doesn't work if I
"9fs sources", right?  My shell's namespace has
something mounted in /n/sources, but rio's doesn't.

Contrariwise, if I plumb "Local 9fs sources" then
I can complete filenames which aren't actually in
my namespace unless I run the command inside the
window.

I'm not expert enough to make strong statements,
but it does sort of feel like something is wrong.
Maybe rfork() needs another namespace operation
in addition to copy/share/blank, something like
"copy on write", so that windows could have their
own devices but inherit additions to the "login
namespace" as they happen?
