It's not just bytecode objects; it's also markers and some other stuff.
The worst case is window configurations, where there's a nontrivial
function compare_window_configurations that Fequal delegates to.

Does anyone know offhand why we don't simply use eq to compare window
configurations? Might save me some work in patching this in master.

I think changing the equal behavior of these objects would be a compatibility change. Maybe we need a single callback based approach for doing both equality comparison and hashing of composite objects.
