I suspect the problem may be on the "identify which process to kill" rather than the "kill it" part, but it's definitely going to take time to figure that out for sure. While the approach killpython takes is much more appropriate, since we don't currently have multiple builds running simultaneously (and for me the machines are dedicated as build slaves, so I won't be having my own pythond), a more blanket kill operation is safe enough. For anyone interested, I caught (well, Georg Brandl caught it first) a case on Saturday with some hung processes on the Win7 buildbot that I was able to verify killpython failed to kill. This was after having a few instances where it did work fine. I've created issue 10641 to track. I also noticed another recent issue (10136) that is also related to killpython missing processes, but given that it works in my case some of the time, and is always called via the same path, not sure if that can be my problem. I also realized that some fraction of the other cases I have seen might not have truly been an issue, since from what I can see killpython is only run at the start of a build process, so hung processes (even killable ones) from a prior build hang around until the next build takes place. They can however, interfere with the svn checkout so things never get to the point of using killpython. So maybe killpython's use should be moved to the clean stage?

Maybe belt-and-suspenders it in both places.
