I scanned quickly through the source of relevant packages. The following lines caught my eye (upstart-0.6.5/init/job_process.c around line 1394):

        nih_info (_("%s %s process (%d) became new process (%d)"),
                  job_name (job), process_name (process),
                  job->pid[process], (pid_t)data);

        /* We no longer care about this process, it's the child that we're
         * interested in from now on, so detach it and allow it to go about
         * its business unhindered.
         */

The comment here is revealing. statd takes care not to let its parent process exit until the child is ready to service client requests. I think the sysvinit startup scripts depended on this. If upstart completely ignores the parent as soon as it has forked, this would introduce a race as per theory B above.
