Extended Description
With python 3.6.8, lit hangs if producing output with non-ascii characters and redirecting to a file on Windows. This can happen if a test fails and has non-ascii in the Script: output. Below I'm using the -a option to show all output to elicit this so it doesn't need to fail.
To reproduce (with revision 689ce81)
python --version
Python 3.6.8
python build/bin/llvm-lit.py llvm/test/Other -a > afile.txt

This should complete in a second or two but hangs instead.
This works fine with python 2.7.15, or with one thread (-j 1), or not outputting the script with non-ascii, or not redirecting to a file.
