Something which occurred to me during the night, we have Client owning
objects running in other threads (for example, DisplayChannelClient),
this means among other things that if we were to
g_object_unref(DisplayChannelClient) from the Client thread,
DisplayChannelClient dispose/finalize are going to be run from the
Client thread rather than from the DisplayChannelClient thread. This
could be unexpected. Maybe it would be better if it was Channel which
owned that reference rather than Client?
