> This will help prevent referenced memory from being garbage-collected while 
> it is referenced by other buffers (for example, in an IPC setting, where we 
> construct Arrow vectors/arrays without copying the input memory).
> Closely related to this: resizeable buffers that are referenced by other 
> buffers should return error status when calling {{Resize}} (if possible).
