 Why do you use Data_Wrap_Struct() ?

 On Solaris 8, for gethostbyname(3)

     The functions gethostbyname(), gethostbyaddr(), and  gethos-
     tent()  use static storage that is reused in each call, mak-
                 ^^^^^^^^^^^^^^
     ing these functions unsafe for use in multi-threaded  appli-
     cations.
