An even better way is to defer the scan until you return to the 
javascript event loop, since then you guarantee the wasm stack is 
empty.

I've long suspected that would work but never implemented it, and 
read a thing just earlier today confirming it would work (but now 
webasm has a new gc thing that works differently google is trying 
to push: https://v8.dev/blog/wasm-gc-porting )
