Yes, and we actually need that in Git for Windows anyway because shooting down a process does not kill its child processes:
https://github.com/git-for-windows/msys2-runtime/commit/15f209511985092588b171703e5046eba937b47b#diff-8753cda163376cee6c80aab11eb8701fR402
However, using this code for `getppid()` would be serious overkill (not to mention an unbearable performance hit because you have to enumerate *all* processes to get that information).

Ciao, Dscho
