      The only usage is here, for deciding whether to take a lock to collect storage stats. The intention was that commands that do not take locks should not take a lock for logging. Although that usage has a deadline in order to avoid deadlock, the PBWM acquisition does not respect the deadlock (SERVER-45007).
