There is no pruning logic on CrdsGossipPull::pull_request_time https://github.com/solana-labs/solana/blob/79ac1997d/core/src/crds_gossip_pull.rs#L172-L174 potentially allowing this to take too much memory. Additionally, CrdsGossipPush::last_pushed_to is pruning recent push timestamps: https://github.com/solana-labs/solana/blob/79ac1997d/core/src/crds_gossip_push.rs#L275-L279 instead of the older ones.
