 151      * on a slow network, this could significantly delay core shutdown [msecs wait * network count].
 152      *
 153      * Here, CoreSession first calls disconnect on all networks, letting them all start
 154      * disconnecting before beginning to sequentially wait for each network.  Ideally, after the
 155      * first network is disconnected, the other networks will have already closed.  Worst-case may
 156      * still wait [msecs wait time * num. of networks], but the risk should be much lower.
 157      *
 158      * CoreNetwork should still do cleanup in its own destructor in case a network is deleted
 159      * outside of deleting the whole CoreSession.
 160      *
 161      * If this proves to be problematic in the future, there's an alternative Qt signal-based system
 162      * implemented in another pull request that guarentees a maximum amount of time to disconnect,
 163      * but at the cost of more complex code.
