For implementers, this promise-heavy design constrains optimization opportunities. The spec mandates specific promise resolution ordering, making it difficult to batch operations or skip unnecessary async boundaries without risking subtle compliance failures. There are many hidden internal optimizations that implementers do make but these can be complicated and difficult to get right.
Each layer catches different attack classes. A namespace escape inside gVisor reaches the Sentry, not the host kernel. A seccomp bypass hits the Sentry’s syscall implementation, which is itself sandboxed. Privilege escalation is blocked by dropping privileges. Persistent state leakage between jobs is prevented by ephemeral tmpfs with atomic unmount cleanup.
