Accesses to this field are gated by `event_map_cs` so I don't think the Interlocked calls are necessary.

Can this happen? I think the event_map_entry would always hold a reference to the event.
I don't see anywhere that events can be removed from the list (unless all events in the list are defunct). There should probably be some documentation of this if it's intentional.

Technically no, this _shouldn't_ happen. At one point I accidentally tested using an HUIAEVENT after it had already had `UiaRemoveEvent` called on it, and not checking this was causing it to segfault. Since that's technically undefined behavior, I guess having this check around is more confusing than helpful. I'll remove it then.

Yes, it is intentional. It's easier to avoid dealing with a removal in the middle of the list by just leaving events around marked as defunct instead. I can add a comment somewhere to clarify this.

Oh, wait, I thought this was in `advise_events`. In the `Release` method, this is more of a potential cleanup behavior. This should be released and set to NULL in `advise_events` when `advise_events` is called for removal. But if that doesn't occur for some reason and the entry is still around, we want to release it.
