To express in a little different words what Colin already said:

Each _wait() invocation in your control thread will sleep until the
next _signal() call from your IO thread. Since your state callback
probably calls _signal() on each context state change this means that
when you are already connected and then call _wait() again you will
stay stuck, because then no more state changes will happen (unless the
connection is terminated, maybe because a cable was unplugged or so)
and hence no _signal() calls either.
