adaptTrashSize() appears to be the sort of thing I'm after..
I suppose I need to do something similar from the createSubThumbnail() method in \
kioslave/thumbnail/thumbnail.cpp ?

The O/S provides this (atime). I guess there's also an (KIO ?) API for getting the \
space used by a directory. From looking at the Trash impl., there are already ways to \
get what is needed for minimal attempt at fixing this ASAP.

As this is a critical data loss bug (because eventually ~/.thumbnails consumes all \
available disk space and KDE gets *very* upset) I'm going with a simple solution \
first (delete everything unused for more than N days). There is a FreeDesktop.org \
spec for this as linked from the bug but it's from 2004.
