New submission from Ma Lin:

My OS is MS-Windows 10 X86-64 (Home edition), with the lastest update (now it's 10586.164).

I have two programs, they occasionally infinite hang.
After a few months observation, I provide these infomation:

1, print() function cause the infinite hang.
2, If it hangs, simply press ENTER key, it goes on without any problem.
3, Both pure-console program and console in Tkinter program have this issue.
4, I tried offical Python 3.4.4 64bit and 3.5.1 64bit, they all have this issue. I didn't try other versions because my programs need Python 3.4+.
5, IIRC, the problem was since Windows 10 Threshold 2 (12/Nov/2015), but I'm not very sure about this.
