If there is such code, I'd say it's poorly written. SUS writes, in the
"Various implementation variations and administrative sequences cause
the set of groups appearing in the result of /getgroups/() to vary in
order and as to whether the effective group ID is included, even when
the set of groups is the same (in the mathematical sense of "set")."
