Duane,
        thanks for your patience. Ofcourse I should have read the FAQ
first. Apparently it's too long ago I read it entirely. I'll go LART
myself after I have read the entire document tonight :)

Yes, I now understand.

What if unlinkd wrote back some sort of "I have deleted this file" notice
and only then the cache file would be marked as available ?

If I had some time left I'd have a look at it, but I'll keep it in mind
as something to perhaps spend some time on.

Mike.
