== AFTER FIX: M6 — 150 concurrent iterations of the real queue RPC vs the real claim RPC on the same file/job ==
queue-side errors:  0 deadlocks, 0 error lines total
claim-side errors:  0 deadlocks, 0 error lines total
(before the fix, the same statement interleaving deadlocked deterministically — see M6-deadlock-replication.txt)
