I've spent a little time looking into this. Plugin creation seems to happen synchronously. Since webkit isn't reentrant in most cases, I don't believe we can do anything involving Javascript while creating a plugin. That having been said, it's a legitimate concern. I'll spend some more time looking through just what happens on plugin creation before landing this CL.
