Ah, ok. We'd need to find all the places in the old document that
reference the node, but that might be feasible.
By tracking all the time, or scanning only upon an adoptNode? Hrm.
We'd only need the Rust references, since the JS ones would be handled
by the brain transplant.
Also, in Rust there would be no references from the normal DOM. And
none from layout, as Patrick says.
So we'd only need to worry about places in the Rust code on the DOM side
that hold references to nodes that are not in the DOM tree. There
shouldn't be that many (e.g. the -moz-element stuff would have that,
perhaps, and things like image loads and whatnot), and we'd have to
teach all of them about adoption. Or do some sort of scan on adopt. Or
something. Either way, in terms of perf the hit would be when adopting
only.
