Kinds of chain reaction "effects": BUTTERFLY, DOMINO, RIPPLE, SNOWBALL
Condition is designed to check the current value when a consumer wakes up. That's fine when state only moves forward, but it falls apart when transitions are fast. When the setter changes state, it calls notify_all(), which schedules wakeups for every waiting consumer.
