Really?  I'd think a cache should be invalidated when whatever is behind
that cache has changed. If this isn't the way it works, it should be documented
in great big red capital letters. If it is already documented, the lettters
need to be redder, bigger and bolder, as I totally missed it. It is 
counter-intuitive for a file system not to stay in sync.

I'd say that this should be the default mode.
