I think this is mostly based on some kind of misunderstanding and quite
possibly because not good enough documentation.
We did have this problem until I fixed it in a way that makes it possible for
you to simply add a handle, and then call the "normal" curl_multi_socket() and
the new handle will be detected and taken care of just fine.
Thus, when you're already "in the game" you don't need to do anything else
than just curl_multi_add_handle() when you add a new easy handle as the normal
loop will adopt the new kid into the family by itself.
