ensure a fallback exists, so use local std{in,out,err} Since IOStream instances require a valid fallback stream, use the locally defined std{in,out,err} instead of sys.std{in,out,err} in IOTerm's __init__ method. Note that the local std{in,out,err} are IOStream instances as well, that fall back to os.devnull
