Sure. But the dir's mtime isn't enough information. Some file might have changed,
which doesn't change the dir's mtime.
This is why, IIRC, we chose to keep the kdirwatch on the cached dir, until the first
"this dir has changed" signal from KDirWatch - at that point we can throw the cache away,
we know it's no good anymore.

However this doesn't help fixing this problem....
