On Linux, SO_PEERGROUPS is an option introduced in 2017, that is, in Linux 4.13. Thankfully, Lix targets 5.10+ kernels minimum. It was chosen to allocate 128 gids by default and ramp up (2x) as needed rather than allocate a full 65k of integers as it seems wasteful. I bet the time to the 16 allocations should incur at most an additional millisecond on a modern system, don't quote me on that though. This is preparation to enable ability for the daemon to vet based on supplementary groups. Related to #968.
