1) document.write is not fast (though of course "fast" is a relative concept).
2) How slow it is depends on what's passed to the call. Just fyi. This has nothing to do with adoptNode.
Agreed. You wrote "(e.g. the -moz-element stuff would have that, perhaps, and things like image loads and whatnot)". Can we (heh, you rather than me) enumerate cases for Servo and rule out a general heap scan?
The set of cases will depend on the exact web technologies, now and future, that Servo supports, and that's a moving target.
But basically, if you're holding a node pointer and you're not its parent/child/sibling, then obviously you'll need to deal with it being copied on adopt if that's what we're doing.... The simplest way to deal is to use a helper of some sort to hold such pointers instead of holding raw pointers.
