First of all, it turns a SEGV into a proper error code. Moreover,
rt_task_join now officially finalizes the object for native (it always
did technically!), as does pthread_join for POSIX. No rule changed, just
rule documentation and violation detection added. One may argue about
join after delete, but for what use case such a change of rt_task_delete
semantic?
