I don't ask for complete explanations of things like "how do I choose stack size", but some information for developers who later look at this code would help a lot (with the current patch, someone refactoring this code would likely just delete this part as dead code).

This is not for JSC stack, but for threads WebKit creates for other purposes like database, html5 worker, blabla.

This was an issue on one of our platforms where the default stack size isn't big enough.

However Rob is trying to working on this with a new bug https://bugs.webkit.org/show_bug.cgi?id=91899
