A 16 GB Apple Silicon Mac running agent sessions, a local Supabase stack in Docker, a `next dev` server and a headless browser becomes extremely slow (load 20+ on 8 cores, 29 GB swap used). Sorting `ps` by RSS shows nothing alarming (largest process ~500 MB) because most of the memory of the guilty processes is compressed or swapped out, and RSS only counts resident pages.

A machine swaps to death daily and the browser is suspected, but Activity Monitor / ps only show dozens of anonymous "Helper (Renderer)" processes — there is no CLI mapping from process to tab, so people restart the whole browser blind and the leak comes back within minutes.
