    # Description of Argument(s):
    # check_out_of_space   If ${False}, a dump will be created and
    #                      its dump_id will be returned.
    #                      If ${True}, either the dump_id will be
    #                      returned, or the value ${EMPTY} will be
    #                      returned if out of dump space was
    #                      detected when creating the dump.
