Revert "Potential thread concurrency issue with WordIterators."

This reverts commit d224c88c480b4493b001f64b59ad37334c00e8dd.

Based on Dianne's comments, this small optimization seems uncessarily
risky. I'll submit a new change where each SpellParser has its own
WordIterator to make this thread-safe.
