You can't run code deterministically in a multi-tenant system.

You can run algorithms deterministically in a multi-tenant system. Only allow tenants to run deterministic algorithms and side-channels are eliminated. Algorithms with provable time bounds can be run and the output delayed until the known time bound to eliminate timing attacks.

Don't you think this is just too much?

does "multi-tennant" also imply "multi-tasking"?

in other words, any system with more than one "task" running concurrently?
