We really need a primitive in Maclisp for doing the Twenex 'abort'-flavor
close on files from Maclisp. Eg, if I am writing to a directory that I don't
have access to and do a (DELETE fileobj) I lose badly but if I close the
fileobj first, I can't DELETE it due to file protection problems. Maybe
(DELETE openfileobj) on Twenex could arrange to do this flavor of close on
the file object? Would that do the right thing? Alternatively, an optional
arg to CLOSE (default T) which if () said to do this kind of close would be
fine also ... Also, GC if reclaiming dead file objects should use this kind
of close if available.
