You can set closeable to True when creating the PersistentDB instance,
then all connections will be closeable. But you usually don't want that.
Instead, the idea is to silently ignore the close and next time a
connection in that thread is requested, reuse that same connection.
When you close your application and all threads are shut down, then the
connections will be closed automatically. Closing them earlier will not
help, since PersistentDB will try to reopen them anyway when a thread
requests a new connection. If the database is shut down, then your
threads get connection errors, and when it is up again, new connections
will be opened again.
