 // On StringImpl creation we could check if the allocator is the StringWrapperCFAllocator.
 // If it is, then we could find the original StringImpl and just return that. But to
 // do that we'd have to compute the offset from CFStringRef to the allocated block;
 // the CFStringRef is *not* at the start of an allocated block. Testing shows 1000x
 // more calls to createCFString than calls to the create functions with the appropriate
 // allocator, so it's probably not urgent optimize that case.
