Comment (by lantti):

 As I mentioned earlier, Windows seems tricky. I had already come to the
 conclusion that python subprocess module is not going to be able to
 cleanly cut this, but, like you said, the next option would be a rewrite
 accessing winapi over ctypes and I don't see that as prohibitive in any
 way. I think I have reasonably good understanding of what timeout.hs is
 doing, but like I mentioned earlier, it doesn't seem to be fully
 functional in the current msys environment. I will slowly keep on
 investigating this when I find free moments. After I come with a patch we
 can discuss how to best test it.
