Did a self-review and found one more issue,
i.e. added is_expired check while in lock
and having detected a valid file otherwise.
If is_expired, we don't use the slot but delete it
and continue filling the new slot.

Additionally I replaced 2 log_level int-literal uses
with the enum LOG_LVL_* symbolic value.
(oversight)

Hope that's it.
Force pushed to above link.
