Whay about backup files.  My application has an option to create .bak files
whenever the user manually saves a file.  The .bak is created by renaming
the disk file foo to foo.bak, and then creating and writing out an up-to-
date file does this mean the alias will point to the .bak file, and the new
file will lose the alias.  It seems that this implementation of aliases is
far to error prone (why not stick to more conventional methods, like keeping
the directory ID and filename or, if you like Unix, the path name).
