You mention that your string is thread safe by design, but you only
solve the problem of mutating the data of a string, your references to
the pieces from which you compose a string are not thread safe, since
they are mutable, right? Or is it that when you paste another chunk on
the end that you get a whole new container and the old is thrown away?
Otherwise if two threads are trying to attach a new piece on the end of
the string you could get out of wack without keeping them from dealing
with the same data structures.
