Over a run of bunch of real world web sites we seem to have ~3% of main thread CPU time in the HTML tokenization and parsing (excluding the actual tree building, the most expensive part). There are surely individual cases much worse than that. This is big enough to support architectural changes like this.

The goal should be to eventually have the whole path from networking on off the main thread and only do the actual tree building there.
