When working with persistent objects, whether they are as yet saved or
not, there is always some other saved persistent object handy, off
which you can get the connection, e.g.

def get_connection(saved_persistent_object):
     return saved_persistent_object._p_connection

This would be slightly different than the global get_connection() --
that would normally require some companion set_connection() to set the
global value (as in general you a module/model may not know anything
about the connection it will be used with) ?
