I think we can only go so far along such a road.  We shouldn't just make
everything harder to use just because we're worried that someone will
ignore common sense and the documentation.  A balance needs to be struck
- you shouldn't deliberately go around creating traps for the unwary,
but good tools sometimes need to be sharp...

A find job may well be too slow, but locate most likely isn't, and an
interactive browser isn't either.  Even find may be quick enough once
lots is cached, so rerunning it a few times may stop it timing out.
