After all, it already exposes the ability to run native code inside NaCl to the web. ;p Will V8 run inside NaCl?

Most of the issues in pdf.js are actually rendering-related, not JavaScript-related—that is, they wouldn't be fixed just by changing the language to native code.

Would that matter for PDFs? I thought js in PDFs is mostly used for form validation, which isn't very compute-heavy.
