Disconnect all signal handlers from a signal?

[Dave Foster <dave foster gmail com>]

Hi all -

I have a situation where I would like to disconnect any signal handlers
attached to a widget's specific signal.  Is it possible to do this
without having to store the sigc::connection object that the connect
method returns?  

It would be nice to simply go signal_something.clear().  If this is not
possible now, would it be possible to physically do sometime in the
future?

Thanks,
dave
