Some code in the stdlib still uses e.args[0] to access errno of OSError instead of e.errno. The latter is more readable, and also it always success (although can return None), but args can be an empty tuple.

Does this issue exist in 3.7.3 too ?
We are observing following traceback, occasionally
The strange thing is that the code at line 674 of socket.py is not the readinto method. But since this bug says that args may be empty, then args[0] would explain the error, isn't it ?
