Well, I wrote the cache, and included the wretched timeout (I wish I'd
never), but my full intention was to make the cache work properly, so that
it didn't need a timeout to deal with all the circumstances when it might
not work properly.

There really shouldn't be any 'back' to be fiddled behind, because the idea
of the lazy walking stuff was to mop-up any changes which hadn't been
explicitly notified and make the cached data right.

At the point I stopped working on it because of other pressures, I'd
completely failed to deal with things going missing (deleted or renamed),
but I'm not sure that they can't be handled properly.

It seems to me that the timeout is either *very* short (like the old cache)
in recognition that the cache is probably wrong a lot of the time, or is
infinite. The way I left it (10 minutes) is not useful at all I
feel. What's it defaulted to at the moment?

Anyway, some of my work pressures are easing-up now, so I might be able to
work on it again shortly...
