I checked Bug 22341, and found no detail of the reason :-)

Anyway, my "Patch 3" is wrong. If no extended encodings are used before starting workers and then extended encodings are used in the workers, multiple threads can enter the HashSet initialization path.

I tried AtomicallyInitializedStatic(), but it produced a build error about global destructor.  So I decided to move these HashSets to TextEncodingRegistry.
