Append the specified handle to the back of this record buffer. Return 0 on success, and a non-zero value otherwise. Note that concrete implementations are permitted to remove records from the buffer in order to attempt to accommodate a pushBack request (which implies that, after a successful call to pushBack, length is not guaranteed to be more than one, and an unsuccessful call to pushBack is permitted to leave the buffer empty).
