Hello, I definitively found the solution to this problem. In fact, there were two problems :
1) bug in thread spawning childs, that you corrected in util.popen3 by sending a message to the main thread to spawn the childs. 2) when you call popen2 class (and others) with commands in pileline, python spawns a child with a shell to start multiple jobs for your pipes : you lose the pid of these jobs and can't kill them later. I found a workaround by setting the shell child a process group leader. I add this line in util.popen3 in Popen4 class in _run_child function : "os.setpgid(0, os.getpid())". Now you can kill the whole process tree by calling os.kill(-child.pid, signal). Maybe useful to add this in util.popen3 and childapp class for future use...
