I''d like to suggest that we come up with some way of opening files for single-use; that is, a way to lock files.  Maybe an interface to the Mesa Librarian from Interlisp?'

How about just opening the file for BOTH or APPEND?  This will keep anyone else from opening it.  Or are you trying to have locks WITHIN the Interlisp-D environment?'
