It seems like shared_from_this may not be enabled when a unique_ptr is assigned to a shared_ptr (although it *should* be enabled when constructing a new shared_ptr from a unique_ptr). Functions that return objects that may need to use shared_from_this now return shared_ptr, just to be safe. Additionally, in some cases, shared_from_this was being called from Thread::run after the last reference to the shared object had been released. We now call shared_from_this during 'open', which will always run on the message thread while at least once reference to the shared object is alive.
