Oh ok, misunderstanding of timer events, they are canceled post call so I
shouldn't erase on callback.

        //  Trigger the timer.
        it->second.sink->timer_event (it->second.id);

        //  Remove it from the list of active timers.
        timers_t::iterator o = it;
        ++it;

        timers.erase (o);
