  It means an attacker with an arbitrary-write vuln needs to be able to target a page as the JITted code is being written to it, rather than being able to target any existing page with code in it.

    And since javascript is so focused on a single thread, it's easy to make sure it's not even running at the same time your JIT code is doing those writes.
