Sounds nice.

I think we put StackBounds in WTFThreadData because of https://bugs.webkit.org/show_bug.cgi?id=102411.
However, right now, we use Fiber Local Storage (FLS) to store TLS data in ThreadSpeific.
Thus, I think the above bug is already fixed: Each fiber can use their own FLS. Fibers do not use TLS in Windows right now instead of FLS.
