I think this is a legitimate concern  (assuming I can get the thing 
working to prevent dual boot) as the System property and file contents 
would still match.  I'm not quite sure how to ensure proper cleanup in 
this case.  There once was a request that we have an option that the 
database shutdown if there were no connections.  That's about the only 
way I can see to resolve it.
