The comment claimed turn concurrency is bounded at admission by
max_concurrent_sessions, but that defaults to unset and auto-resume is
uncapped. The real bound is one live turn per session plus turns
abandoned by the inactivity timeout, whose threads keep running. Say so,
and note in the max_concurrent_sessions docs that it is the only cap on
concurrent gateway turns.
