commit https://github.com/vim/vim/commit/f92591f7f9fc78d2aced99befe444cb423b26df8 Author: Bram Moolenaar <Bram@vim.org> Date: Wed Feb 3 20:22:32 2016 +0100 patch 7.4.1248 Problem: Can't reliably stop the channel test server. Can't start the server if the python file is not executable. Solution: Use "pkill" instead of "killall". Run the python file as an argument instead of as an executable.
