The only thing that seems really significantly parallel is the error
message to be issued for object-not-found. I would suggest maybe
putting the code in lsyscache.c, except that lsyscache functions
generally are not expected to throw error on object-not-found.

As for "not every object type has a file", there is certainly code
someplace that would be calling these functions. Whereever (the
preponderance of) such calls are would be an appropriate place for the
function, IMO.
