Make sure you have your driver cache set to "none". I've seen similar
things happen with other cache settings, but with "none" it works just
fine (but of course that might impose an i/o performance penalty in
some cases?). I think the default is "unsafe" in 0.9.7 and later? It
would be nice if the cache settings were documented more clearly.
