Detailed Description

Per-thread policy stack.

The stack lives in thread_local storage. Each thread has its own stack, initialized with a default-constructed base entry that is never popped. RAII guards (Guard) push and pop policies.

For thread pool workers that don't inherit thread_local storage, the policy must be passed into the lambda and pushed onto the worker thread's stack when the task starts.
