or we could do what we do for a bunch of other atk methods reutrning
const gchar* nd use nsAccessibleWrap::ReturnString() which keeps a
static nsCString and returns a pointer into its buffer, and so requires
caller of atk method to copy returned string before calling another atk
function, which I think its very likely the bridge will always do.
