I presume they are intended to use for caching. If the thread does not changed,
it can use the cached value in the static variable. Since webkit is designed to
be single threaded, the detecting of stack base becomes faster.

Unfortunately, there are still other crashes with V8, and WindScorpion
(SunSpider is ok now). Corrupted double-linked list detected by malloc, or
infinite loops happen frequently. How the Workers were tested in the past? Were
they added by Google without testing them on JavaScriptCore?

I hope I can find a way to make JSC thread-safe, but I would appreciate any
help from you (I can attach the other benchmarks as well).
