A combination of the two sounds best to me.  Use `notifyFinish` for now, 
and file a ticket asking for a public version of `_disconnected`.  When 
that's done and has been released for long enough, Nevow can switch (if 
anyone cares enough to do it - presumably the only reason anyone would 
care is that using `notifyFinish` might add a miniscule additional 
amount of per-request overhead).
