Master -> Slave SYNC is performed via RDBs.
RDBs are generated by child process that should touch as little pages
as possible, and can't change parent's memory anyway, so there is no
expiration process: simply keys that are found already expired are not
persisted at all, of course.
So a Master can have N keys in memory that are already expired but are
still to be "collected", but the slave wil not have these keys as the
RDB was purged.
