Besides being a security issue, it slows down the entire TLS ecosystem.

Building a container via GitHub Actions, it suddenly occurred to me that I can hasten the build by... not building for amd64. It's been a default for so long, but neither my laptop nor the builder nor the cluster the container lives on speak that architecture.

Another one for Tailscale Hack Week:
I got Go ported to Redox OS (www.redox-os.org), enough to run Tailscale inside it.
i.e. GOOS=redox GOARCH=amd64
Go std tests exposed a Redox libc bug with unsafe Rust, too. And a kernel crash.
