I have made now a lot of tests with the new signals2 library. The only 
thing because I don't want to use it now, is because it is really slow...
I have made now performance tests with the dummy_mutex which is included.
I have found out the about 50% of the time that it takes to call 
10000000 is inside in slot_call_iterator---->lock_next_callable 
function. Here the follwing lines takes the 50% of the executing time:

             lock_type lock(**iter);
             tracked_ptrs = (*iter)->nolock_grab_tracked_objects();

I hope that one has an idea how it can be made it faster...
