Nope. There are handlers and there are cleanups, the later is an
optimization of the first. We have a chain of handlers, and each
handler can have a chain of cleanups. Since we cannot have cleanups
associated with NULL, we must have an empty end of chain handler to
have a chain of cleanups associate with it.
