     The solution is simple.  Instead of saving the working directory
reference number, save permanent information which can be used to find
the place where the file is.  Save the volume reference number and the
directory ID of the folder where the file was found.  You can use
PBGetWDInfo or the new GetWDInfo glue for this purpose, once you have
the working directory reference number.  Then close the working
directory, since you won't need it until you look for that file again.

     If anyone tells you to save the pathname, don't listen.
