Hi!

I have a not yet understood deadlock in a Xenomai application on my desk.
It looks like the deadlock is caused by the fact that rt_task_suspend()
can cause the calling thread to exit.

So, a thread puts itself into suspend and never returns (and exists).
Debugging indicates that ret =3D __RT(kill(pid, SIGSUSP)); in threadobj_sus=
pend()
is the place where it enters the kernel and never return and inside the
kernel exits.

Can this be? :-S

Thanks,
//richard
