Yeah, but I like to split these out so that if this does break something,
it's much easier to revert. In case I overlooked something somewhere.

It's imo different if the cleanup is directly related to the preceeding
prep work, but this is a generic workqueue, and the cursor logic is rather
unrelated. And if I remember my history digging right, there were actually
other uses of this.
