If this happens, then there is a problem in your application. Part of
the things required of your application when writing an application for
a dual-kernel solution is to let the other kernel run from time to time.

AFAIK, there is one in the linux kernel itself. The linux kernel uses
separate objects (clocksource and clockevents) for hardware clocks and
timers.
