Hmm, in theory it should be no problem to call rt_task_suspend(task)
with task != NULL from arbitrary contexts. But the native skin prevents
this. I must confess I do not know the reason behind this right now. The
point is that you do not need to block for remote-suspending some other
task, thus the caller's context should not matter. Anyone else any idea?
rt_task_resume() in contrast is fine from any context again.
