I applied the patch from attachment 256835.
That was a huge improvement in performance.

My system is has a bunch of stuff open right now so I can't run a clean benchmark, but JSCore has gone from 120 sprites to about 4100. For comparison, the Lua benchmark currently runs at about 10000 sprites.

So this is a terrific fix. I'm still wondering if there is something more that can be done. The differential here between Lua and JavaScriptCore still seems a little wider than the other platforms.

But thank you. This finally makes JavaScriptCore usable on Windows.
