If we make a separate thread-safe code path, I’m not sure we need to create a
variant of AtomString at all.
AtomString optimizes string comparisons (by paying up front every time you
construct one with a hash table lookup) and memory use (by sharing the same
memory for all equal strings), but there’s no reason we can’t compare two
strings without using AtomString. I’m doubting that once we figure out what
we’re trying to do that we’ll need AtomString.
