 // 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.
