[boost] [signals] slots bug?

Hello.

Investigating a problem Elisabeth Benoit was having at the users mailing  
list I've come to this code, that doesn't work as I would expect:

#include <boost/signal.hpp>
#include <iostream>

void func()
{
     std::cout << "pp\n";
}

int main()
{
     boost::signal0<void> signal1;
     boost::signal0<void> signal2;
     boost::signal0<void>::slot_type slot = &func;
     boost::signals::connection conn = signal1.connect(slot);
     signal2.connect(slot);
     conn.disconnect();
     signal2();
}

The func() free function is only called once, because disconnect() removes  
the slot from both signals.

I'm not sure if this is a bug, but I would expect slot_type to work as  
boost::function.

Regards,
Bruno
