UCALL_UNHANDLED is a bit of an odd name. Without the surrounding context, I would
have no idea that it's referring to an unhandled event, e.g. my gut reaction would
be that it means the ucall itself was unhandled. Maybe UCALL_UNHANDLED_EVENT?
It's rather long, but I don't think that will be problematic for any of the code.
