Summary:
It's just bad that we give a naked pointer of the connection manager to other instances. If the connection manager gets deallocated, the instances keeping a pointer to it are doomed to crash.
This change creates a wrapper on top of the pointer that can be freely shared. On deallocation, the shared wrapper gets invalidated.
