Such conventions can be layered portably on minimal Posix by using the
file namespace hacks in the vu_ modules.

There is, indeed, a module there that, if installed by the client
application, treats opens of `-' for reading as descriptor 0 and for
writing as descriptor 1.

It's not that the `-' convention is one to etch in stone (though I
like it, personally) --- just that a portable mechanism is there in vu
so that if a convention is settled upon, it can be hacked up in `vu'.
