Subject: [Xenomai-core] [bug] user memory leakage on rt_task_delete

Hi all,

during my ongoing search for the init/cleanup issue of shadow threads, I
stumbled over another problem: Deleting a userspace native thread that
is blocked in primary mode does not let the NPTL clean up all resources
allocated in userspace. If you plan to do some rt_task_create/delete in
a loop, you will soon run out of memory (and Mr. oom-killer will show
up...).

I haven't found a solution for this beyond letting a rt-task always
terminate itself (or terminate the whole program after forced
deletions). If there is no solution, we should at least document this
fact somewhere.

Again, it's not a common use case, but it's also not an expectable
behaviour of the native skin.

Ok, back to work,
Jan
