62626363-We're building an AT Protocol relay ([zlay](https://tangled.sh/zzstoatzz.io/zlay)) that runs ~2,800 concurrent fibers on `Io.Evented`. We've been working around this by building with ReleaseFast, but recently a separate bug (a websocket off-by-one) manifested as a silent SIGSEGV under ReleaseFast for weeks. ReleaseSafe would have caught it immediately as a bounds-check panic with a stack trace.
