This type of data needs to obtain internal mutex to get the values. (log_sys->mutex for this case, because "age" is relative data of 2 values)
Currently, the values of the "show status" doesn't obtain any internal mutex other than "&srv_innodb_monitor_mutex" (at least 5.5.8).
I think we should not add values which needs other internal mutex to get the value.
(unwilling deadlock, or performance problem by "show status" might be occur)
Or, completely wrong value is acceptable?
