 160      * on a slow network, this could significantly delay core shutdown [msecs wait * network count].
 161      *
 162      * Here, CoreSession first calls disconnect on all networks, letting them all start
 163      * disconnecting before beginning to sequentially wait for each network.  Ideally, after the
 164      * first network is disconnected, the other networks will have already closed.  Worst-case may
 165      * still wait [msecs wait time * num. of networks], but the risk should be much lower.
 166      *
 167      * CoreNetwork should still do cleanup in its own destructor in case a network is deleted
 168      * outside of deleting the whole CoreSession.
 169      *
 170      * If this proves to be problematic in the future, there's an alternative Qt signal-based system
 171      * implemented in another pull request that guarentees a maximum amount of time to disconnect,
 172      * but at the cost of more complex code.
