Found out through some testing that I had to call the Read() method during the loop in order to have the SlaveProcess recognize that it was finished.

int Ping(){
  String ret;  // <-- Added this line
  String cmdline = "ping -n 3 192.168.0.1";
  One<SlaveProcess> sp = StartProcess(cmdline);
  while(sp->IsRunning()){
    Sleep(200);
    sp->Read(ret); // <-- Added this line
  }
  return sp->GetExitCode();
}

This works now.
