While you step though a Xenomai task context, timers continue to tick.
So the period spent in that context gets huge, and soon the task will be
shot by the watchdog. Likely a limitation of kvm (interrupts should be
blockable in singlestep mode). Haven't looked at all details yet, just
picked the lazy workaround.
Of course, we don't use this value on real HW.
