Use caml_alloc_string(n) to create an *uninitialized* Caml string n 
bytes in length.  At least one zero byte will be provided by the Caml 
runtime at the end (possibly more, based on alignment issues).

caml_copy_string is a full physical copy (terminated by the first 
encountered zero byte) of the supplied string - there is no "sharing".
