I could, but I'm still dealing with the constraint that records can
never be deleted: #2.  Also the fact that there is no way to simulate
certain conditions is also painful.  A good API should have a way for
me to simulate an error, no?  I'm getting by with little or no tests
around this code, but I don't think it will last for long...
