> When there are many messages in a queue, the messages are (by default) paged.
> However, when all these messages expire (given that a TTL is set), and there are no consumers, only the in-memory messages are removed. This leaves all paged messages in their on-disk state, thus preventing further actual message expiry.
> Is it possible to add a function where messages are paged-in more often? e.g. when the in-memory part of the queue is empty during an expiry-sweep. This is useful even when only one chunk is paged-in to not keep the expiry-thread unreasonably busy. This will eventually lead to the actual expiry.
