|Subject:||drop_gid_perm does not alter supplemental privileges|
Mark Grimes discovered that when calling the drop_gid_perm() function provided by Proc::GID, supplemental groups are not dropped. This is contrary to common expectations, and may result in proceses retaining privileges they had intended to discard. Proc::UID should be modified to provided a way to drop supplemental groups. This may involve changing the behaviour of the drop_gid_perm() call.
