The `&event->event->deliver` one is inside a lock anyhow (and its use is kind of strange, but any comparison to it is happening inside the event lock too).

The other uses of `__ATOMIC_RELAXED` are for increasing refcounts, which are always starting at 1, and the only point a full barrier should be needed is to check for destruction, where we still have `__ATOMIC_SEQ_CST`.
