New submission from Simon Depiets <sdepi...@gmail.com>:
A couple of users have been having issues on console output since the Fall 2017
Creator Update on Windows 10
An OSError is triggered randomly when rewriting data on the console (typically
with progress bars, for instance when you install a module with pip), this only
happens with the Microsoft Console (within Powershell or cmd.exe).
It seems the windows stdout console stream returns a length double what python
expects. I don't have the skills to go deeper than the bufferedio.c method
_bufferedwriter_raw_write to diagnostic the issue, so I've made a very dirty
fix (which I do not recommend)

Different unrelated use cases where an error is triggered :
