> When working with a VectorSchemaRoot, once it is no longer needed it resources are freed by calling {{close()}} followed by then closing the allocator.  Sometimes it is needed to close a second time due to complex operations.  If the VectorSchemaRoot is closed again after the allocator, it raises an assertion error during {{clear()}} because it is trying to allocate an empty buffer, which ends up being destroyed immediately anyway.  The {{close()}} operation should mean that the object is no longer to be used, so once closed it should not try to reallocate it.
