      Companion artifact for SERVER-75430 (TicketPool / PriorityTicketHolder polls checkForInterrupt every 500ms; killOp/shutdown can stall behind polling timer).

      TLC verified: good cfg 94 distinct states clean; bug cfg produces 6-state liveness counter-example. Fix sketch: `waitForAtomicOrInterrupt(opCtx, atomic, predicate)` joining wake sources via futex(2) waitv.
