Thanks for the link! But do I really have to collect and maintain various  
connection objects for a signal? There is out-of-the-box support for  
attaching callback functions to a signal. But in order to detach them I  
have to maintain the connection objects for all the callback functions  
myself? What's the rationale for this? Or is there is any utility class in  
Boost.Signal I miss?
