Previously, both the connection handlers and + the transports had their own reference counting mechanism and + independent lifetimes. The reference counting was inadequate + since it was not originated at the Reactor and the independent + lifetimes unnecessarily completed protocol specific transport + code. <p> + + The changes couple the lifetime of the connection handler with + that of the transport and utilizes the reference count in the + base ACE_Event_Handler class. This allowed us to remove several + hacks throughout TAO code which were designed to prevent (or + delay) crashes.
