[okl4-developer] iguana scheduling security question

Hi okl4.org,

Please correct me if I'm wrong, Isn't the fact of every iguana's thread
being able of setting it's own scheduling parameters as seen in thread_setup
L4_ThreadControl(self->id, pd_l4_space(pd), self->id, L4_Myself(),
L4_Myself(), 0, utcb);, where scheduler is set to be their selves, a
security issue?, since there will be no way to prevent one thread of
becoming it self a system starving thread.

Thank you very much,

Jorge
