Would be better, I think. Otherwise, at least xnpod_delete_thread and
also rtdm_task_destroy would require a clear warning sign.

I was not aware of this restriction, so I did not worked around it in
RTnet - which is easy at RTDM level BTW: task wakeup for
self-termination + rtdm_task_join_nrt. This is cleaner anyway, so I will
patch RTnet now.
