Well, I think I have to disagree with me here. :*)

Looking at hurd/hurd/io.defs, this parameter is specified as

  out data: data_t, dealloc;

Maybe I'm just understanding the MiG documentation wrong, but I thought
the "dealloc" would take care of exactly this case. (Which was probably
the reason I originaly wrote the code the way I did).

But then I don't understand why the glibc code copies the data back from
the newly allocated space to the old one (provided by the client).
