+Two or more async memos whose answers resolve in the same tick as a plain write re-asking them are all answered, then re-asked (D-22, #4495): a memo over them reads every answer through `latest` and is pending on the re-ask. An earlier landing's flush no longer re-asks the others before their answers arrive, dropping them.

+/**
+ * #4495 (D-22, F-9, F-10): two async memos m1, m2 both answer, then a write re-asks them,
+ * all in one tick. The memo c = m1() + m2() reads both answers through `latest` — 2 + 11 = 13
+ * — and is pending on the re-ask: both answers resolved before the write, so both are produced
+ * values (D-22: answered, then re-asked), whichever reaction runs first.
+ *
+ * Cause: an async landing flushed synchronously (`asyncWrite`), and that flush carried the
+ * queued write: it re-asked m2 before m2's answer's reaction ran, so the answer arrived
+ * superseded and was dropped. A landing that arrives while a write's flush is queued is now
+ * carried by that flush (F-10), with every answer whose reaction is queued ahead of it.
+ *
+ * From the review repro 4459c-two-sources-landing-order (re-review of #4459).
