Before asking this question I had assumed AtomicString was an atomic
type <http://en.cppreference.com/w/cpp/atomic/atomic> (as in, safe to
use in multi-threaded code). InternedString would have been more
obvious, but the biggest problem was that searching for "WebKit
AtomicString" didn't return any results that explained what it was. Now
the top hit <http://trac.webkit.org/wiki/EfficientStrings> has an
explanation, so it's not a big deal.
