Please correct me if I'm wrong, but I thought that the write barrier applies to assignments of SEXP values only (from the doc: "... must be used for all assignments of SEXP pointers ..." - note it says "of", not "to"). When dealing with REAL/INTEGER, I believe it's still safe to use INTEGER(x)[0]=... IMHO that's logical, too, because primitive types have no 'age' to be inherited when using ggc.
