    Returns a response if this handle has finished execution, otherwise returns null.
  - getStatus
```
Status getStatus()
```
    Returns a status object for the current execution. This will likely be the same object that would be returned as a component of the Response value. Never null.
  - cancel
```
boolean cancel()
        throws LockTimeout
```
    Attempts to cancel execution of this Request. Returns true if cancellation was successful. Returns false if not, in which case likely this request will run to completion.
