41  * OperationExecutor that checks for FU resource conflicts.

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.
