When that didn't work and I made sure the table, index, and column stats
were correct, I tried various hints for join order and join method. When
that didn't work, I decided to smack Oracle in the face with the answer like

SELECT ...
FROM (SELECT ... FROM A, B WHERE ...) AB, (SELECT ... FROM C, D WHERE ...)
CD
WHERE ...
