Ok, now I see that my object is being copied. But for the lines :

        FakeClass *item1 = new FakeClass(1);//,item2(2);
        group.create_thread(*item1);

I get :

FakeClass #1 says : I'm alive!
FakeClass #1 says : Being Copied!!
FakeClass #1 says : Being Copied!!
FakeClass #1 says : Being Copied!!
FakeClass #1 says : I'm being destroyed!
FakeClass #1 says : I'm being destroyed!
FakeClass #1 says : Being Copied!!
FakeClass #1 says : I'm being destroyed!
Thread for FakeClass #1 has been started!
FakeClass #1 says : I'm being destroyed!
   main ending...

The copy constructor is called 4 times!!! And it is called 3 times before 
the thread has even started! Is there a way to avoid that ?

I was going to use the thread_group to manage the connection to a simple 
server applications, so that all the threads would hold info about the 
socket used for connection, etc... And that if the objectdestructor is 
called, the connection to the socket would be closed... With my object being 
destroyed 3 times before the thread has started, it gets a bit hard to 
manage that way... Any clue on how to use the threads so that it would work?

thanks,

Simon
