Such parallelism is great, but just to clarify I was more thinking about
having the new system work concurrently with the rest of Elisp.
I.e. have one CPU run Elisp while other CPU(s) do the syntax processing,
whereas a naive use of tree sitter's parallelism would end up with
either Elisp running alone or tree-sitter using several CPUs but never
both at the same time.
