Hi,
I just stumbled across an ambiguity in the documentation for
rt_task_delete() in the native skin. One could think that this function
can only be called from userspace if it is a RT task because of

I've spotted a -- in my view -- strange behaviour of RT pipes in the

task deletes the pipe.

on page 21 of Native-API-Tour-rev-C.pdf one gets the impression that
