41 * OperationExecutor that checks for FU resource conflicts.
42 *
43 * This kind of OperationExecutor is created for each operation in the
44 * simulated FU. This is purely for optimization purposes: as we need to
45 * check the resource conflicts using a per operation ID, it's faster to
46 * use a constant ID for requesting the conflict detection data instead of
47 * first fetching the constant from a map for the executed operation.
