I tried, but it doesn't work.  Both shells are put on the calc using
backups, so if you send one of them you erase the other.

I don't know the specifics, but in Ash the authors seem to use L1 (list 1)
instead of Q.  If you try to delete L1 in Ash, you calc will crash, just
like deleting Q does in OShell-82.
