We have three threads for some rare events by now if I count correctly.
That is
- mce check on x86 (mce_notify_helper_thread)
- this one
- clock_was_set_delayed() (pending)
So right now I am thinking about a workqueue for rare events because if
I keep doing this we end up with a bunch useless tasks for something
that might never occur.
