As others mentioned, you don't want to create the ref detatched in
case you would like to join later or whatever. There can be an
explicit detach() method to detatch right away if you like (in fact
I'd say there should be). The point of having it in the destructor is
just for the purposes of normal resource management: if you don't do
anything explicit, resources will still be freed correctly (ex. in
Win32 detach is implemented as CloseHandle() which would cause a
resource leak if not called).
