The problem is I was using Windows, and I am not very familiar with that
system. In Linux, the child would have died automatically.

I think it would be much easier in practice if the program made sure
it does not keep running when its parent process (kgsGtp) dies. This
can happen in multiple ways - either by doing this explicitly,
http://stackoverflow.com/questions/284325/how-to-make-child-process-die-after-parent-exits
has a couple of ideas, but even a much more elegant way is simply not
overriding SIGPIPE. Then your process will get that signal when trying
to reply to a deceased kgsGtp and die automatically.
I suspect these problems stem from disabling SIGPIPE which really
shouldn't be necessary for anything in this context anyway.
