thanks, I'll do it.

I have firstly implemented it because I wanted to take care of that
case but I agree it is a very uncommon case.  Then I realized that
set_state can also be useful if we intent to support "Modify connection"
in future (not really sure it is useful).

Would you accept the patch if I combine reset_state in set_state, so
that set_state will accept a set_to_default argument?  If you still
think that the cost of maintaining the new code is bigger than the
advantage of fixing that particular case, I can drop set_state.

Thanks,
Giuseppe
