DB modules following DBAPI2 must define the following attribute:

"""
  threadsafety

            Integer constant stating the level of thread safety the
            interface supports. Possible values are:

                0     Threads may not share the module.
                1     Threads may share the module, but not connections.
                2     Threads may share the module and connections.
                3     Threads may share the module, connections and
                      cursors.
