You quoted me raising two different concerns; I'm not quite certain
to which you are responding.

Assuming you're responding to the first (reusing location), which
seems more likely: you mean "scan" only in the sense of "scan the
meta-data table," right? Not "scan all the files in the requested
target ("www" in my example, over and over), comparing to the
text-bases in the putative meta-data"? Because, of course, (1) in my
precise example, there's no "www" to scan, and (2) if there *were* a
"www" in the way, it might be really darned huge....

Assuming you're responding to the second (miscellaneous left-over
meta-data), which seems less like a match to what you say: do you
mean to check all known wc locations for existence? And possibly
clearing out meta-data for unfound wc's? I'm thinking new horror
stories involving temporary tar/zip/gzip action on existing wc1 to
make room on my crowded disk for wc2; wouldn't want some operation on
wc2 to silently remove the wc1 metadata.
