And embedding means making the layout (at least the size) of
PeriodicTimer public. I guess that's why QEMUTimer works via new.
Why do we care? We don't have an stable module interface.
(the way to provide a size-stable interface is
struct PeriodicTimer {
struct PeriodicTimerImpl *impl
};
though of course it negates some of the advantages of embedding).
