That's why I put "zle -D zle-line-init" in there.  The widget executes 
once (the first time zle initializes) and then ceases to be a widget, so
it never executes again.

I presumed you had that somewhere already, because of the implementation
you had included.  I didn't know what you called it so I made up a name.
I supposed e.g. that you had pasted in the content of an autoload file.

The full solution (with apologies to others that this repeats most of my 
previous post) could all be in .zshrc and would then look something like

    grow-killring() {
        setopt localoptions noksharrays
        : ${killring[${NUMERIC:-30}]:=''}
    }
    zle -N grow-killring
                                                                                
    zle-line-init() {
        zle grow-killring
        zle -D zle-line-init
    }
    zle -N zle-line-init
