Description

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).
