It can happen (by line CurSU->isPending = true; // This SU is not in AvailableQueue right now.) that a SUnit is mark as available but is not in the AvailableQueue. For SUnit being selected for scheduling both conditions must be met. This patch mainly defensively protects from invalid removing a node from a queue. Sometimes nodes are marked isAvailable but are not in the queue because they have been defered due to some hazard.
