Yes, I realize API version != file version.  What I was getting at was that
if I did something like

    db = bsddb.hashopen("foo", "c")
    db["1"] = "1"

under the old bsddb module using Sleepycat 4.0.14, can I be assured that

    db = bsddb.hashopen("foo")
    print db["1"]

will work with the new bsddb module?

There should be no surprises in the common case, yes?
