Ah forgot to delete the "Also" part. I wanted to write that it moves the 
evaluation away from inside the read_mems_allowed_begin() - 
read_mems_allowed_retry() pair. But then I realized it's just taking a 
*reference* and not going through cpuset_current_mems_allowed yet, so 
it's probably OK. Just out of place in this patch.
