It no longer seems to loop endlessly. I get one batch of events from the "since" to the "until" and then and EOSE, and nothing else.
If "since" == "until" then no events are delivered, and no EOSE comes, even though there are events with that time code.
For example this REQ delivers no events and no EOSE:
["REQ","ms-past",{"since":1677844901,"until":1677844901}]
However, there are events with the ...901 time code (that I got with a different query) e.g.
["EVENT","ms-past",{"id":"a864e19e925bce1ed8f1ef0cde918e55182f6b1e93ac37a8c09b3cdf60d6e6e4","kind":9735,"pubkey":"be1d89794bf92de5dd64c1e60f6a2c70c140abac9932418fee30c5c637fe9479","created_at":1677844901,"content":"","tags":[["p","2c7cc62a697ea3a7826521f3fd34f0cb273693cbe5e9310f35449f43622a5cdc"],["bolt11","lnbc220n1pjqrcvmpp5uf5svph5snesx5jrchjjevxum023t3wfk3fnvyevfkvfvwsh07lshp5zlz2mflru26grw6jy9450eavtrqd95egs8a2jxa6kmqfwgkhxlcscqzpgxqzfvsp59jgkqte57rzj34wdea7g502eufv56yt4wy3ftddtm6gcalvz8vxq9qyyssq43jfpsryh6ryua0gnekghm0j4le7706c6tprry86q82zpnzcx66qe6nhrdg22j4dqmwm5h7gd38lwqfrjkcjxujx4ur327nvj8v2kusq2jpzxx"],["description","{\"kind\":9734,\"created_at\":1677844890,\"tags\":[[\"p\",\"2c7cc62a697ea3a7826521f3fd34f0cb273693cbe5e9310f35449f43622a5cdc\"],[\"relays\",\"wss://nostr-pub.wellorder.net\",\"wss://relay.damus.io\",\"wss://nostr.jatm.link\",\"wss://nostr-relay.nokotaro.com\",\"wss://nostr-relay.aapi.me\",\"wss://nostr.21crypto.ch\",\"wss://relay.snort.social\"],[\"user\",\"grimyend76\"],[\"amount\",\"22000\"]],\"content\":\"providing zaps for free | donate: zappr#[15].dev\",\"pubkey\":\"c6ee20a53f29409e1d0bb39edf6d0d3377e9a7133aba4d467db83f8d33d0ea06\",\"id\":\"47234ce73a5a2563dce90507bc9ac237d02c9adf3699f784ce1fb6f2e608335a\",\"sig\":\"e788057275671a404b67fb1dece2673bda01915727ed960de11f77865a9e3d78e18f590119ef0296401ff7f35053ffad67f37583aedf28641e8037d26a1e3d06\"}"],["preimage","e2690606f484f3035243c5e52cb0dcdbd515c5c9b45336132c4d98963a177fbf"]],"sig":"5651c0b9fc6bb0950534f67db8f16c58958966833d0eb315b962684f22b622966d858303e454a495f01a0723c6d5fee639a4aaddbecdbefd2d32872e775523e7"}]
