It all looked reasonable to me. People there were thinking about this as a possible fix for a hypothetical crash, not a security issue, and no one was able to prove that there was a crash, nor that the patch fixed it. No one bothered reviewing it, and the original person who raised the patch didn't advocate further. None of this seems even close to "insane", this seems like exactly what you expect in most software projects. "Hey, can you explain the bug this patch fixes more?" -> contributor vanishes into the aether -> nothing happens.
