Overview

generation: the pool generation a worker was born into; shutdown!/fork bump the generation so a worker checked out under the old config is retired (never re-pooled) when it returns. owner_pid: the process that spawned it, so a worker inherited across fork is never killed by the child (it belongs to the parent). tmproot: a parent-created directory the worker puts its per-operation tmpdirs under. The worker removes it on graceful exit (at_exit); the parent removes it when it kills the worker, so a SIGKILL mid-operation (where the worker cannot clean up) does not leak the op’s tmpdir.
