Comment (by dnadales):

 Thanks for checking this out. I've tried your example with GHC 8.2.1, and
 it also hangs when killing the reader. I'm also running a 64-bit version
 of Windows 10, so I don't know what might be happening.

 How did you launch the two processes? On a Unix like terminal emulator?
 (I've tried on MINGW64, but there it is even worse since I don't see any
 output). In my case I was using Windows Power Shell, but I get the same
 result in the old Windows Command Prompt.
