JavaScript/HandlingThreads

In Firefox 4, JS extensions using nsIThread.dispatch won't work the same way they have in the past. The purpose of this page is to document the design choices we have, so we can get to a decision, late though it may be.

1. MT Proxies
2. ChromeWorkers w/ usable Constructor
3. Nothing
4. Environment cloning
5. structured cloning with WrappedNative handling
