Well, no, you have to reset them, the same way you set up the paths in
the first place.  Use close and dup to put stdin and stdout back on
paths 0 and 1. (Look at lootterm2 again, the first thing it does after
os9fork() is put its paths back the way they started.)

That you would have to experiment with... I'm not sure.
