I don't think the storage should get involved with this. There are alot
of knobs and possible policies that can be used. This is all well documented
and supported by Sleepycat Software. IMO, when someone uses a Berkeley DB storage
they are using Berkeley DB and should learn how to administer it. I don't
think it's a good idea to try to hide this from people.
