Right. One of the things that v5 does is to move the master map parsing out of the init script and into the daemon itself. That means that the daemon then has to manage each of the master map mounts as well. Using individual sub-processes has a whole set of problems related to the supervising process communicating with and knowing the state of those sub-processes so v5 changed to a threaded model which of course has it's own set of difficulties.
