I thought about that. But you could also argue that next_event() is also
a kind of start for the timer. Actually, if I was to change anything
about the naming, I'd turn stop to teardown.
And not changing the naming makes the patch series smaller and more
easily verified.

I tried. It's actually uglier without the ifdef...
