Slightly tangential, but why doesn't Linux symlink /dev/random to /dev/urandom like OpenBSD does?

Wouldn't that stop issues like these (what's the benefit in keeping /dev/random the same)?

Extreme backwards compatibility. An application might depend on the blocking behaviour (be it sensible or not). And since it's a change visible from user space, it won't be done (except in extreme circumstances).
