It can take a couple of hours under pretty heavy load to get one
occourance. But with preemptible context swiches off we haven't seen
any in a week.
For sure xenomai tasks are handling interrupts quite a lot at the time.
I wish we had a simple test case to show it, but it seems to require
triggering an interrupt in the middle of a context switch at exactly
the wrong place.
