I now realize, that locking is out of the question. Also, it has been
suggested to use per cpu stats and overflow into a global counter. (Thanks
Zwane) This might be a better idea - the problem is, the counter won't be
100% accurate at all times. The degree of inaccuracy will vary with the
threshold value. On the other hand, if the threshold is relatively low, no
one will notice the difference these days.
