The problem was a few points:
* We were not clearing the reactor on a normal stop, which is what
is used in a phased restart.
* On close, SSL sockets were not sending the shutdown message.
* SSL sockets that were completely uninitialized ended up sitting
in reactor and could not actually be shutdown because there were
not initialized.
