Both forks ran this script at once on 2026-08-21, each with ninja -j$(nproc)=16. 36 cc1plus held 42 GB of a 62 GB box, the kernel OOM-killed for 2h28m, ssh went unreachable, lightdm was destroyed (2946 session kill events), and neither build produced a single object file. Three bounds, weakest to strongest: a flock on a path SHARED by both forks so they serialise instead of summing; -j8 so the box stays usable while it compiles; and --memory on the container, which is the actual guarantee — a runaway build now dies inside its own cgroup instead of taking the host with it. --memory-swap is pinned equal to --memory because swap thrash is what made ssh hang rather than fail. Kept byte-identical to the copy in the snaporca fork, as the header requires. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
