Detection is via allocating a slice of zeroed memory, in our case a gigabyte, and then once per minute going through to ensure they're actually all zeroes. Magic!
There is a lot of energy right now around sandboxing untrusted code. AI agents generating and executing code, multi-tenant platforms running customer scripts, RL training pipelines evaluating model outputs—basically, you have code you did not write, and you need to run it without letting it compromise the host, other tenants, or itself in unexpected ways.，这一点在91视频中也有详细论述
