Thinking back on this, this still has the issue of not preventing preloads.
Again, preventing preloads on a per-load basis is a hard problem if you
want to have sane parallelism. Preventing _all_ loads for a document
based on some declarative thing near the start of the document, on the
other hand, should not be too bad. If that plus a beforeprocess event
addresses the majority of the web-facing use cases, we should consider
adding that.
