- `killBehavior` - Dictates if your async unit (worker/process) will be deleted in case that a task is active on it.
**KillBehaviors.SOFT**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still running, then the worker **won't** be deleted.
**KillBehaviors.HARD**: If `lastActiveTime` is greater than `maxInactiveTime` but a task is still running, then the worker will be deleted.
