There's no need to enumerate every single process to do this. On *nix, you could check if the directory /proc/<pid> exists. If so, the process is alive. On Windows, you could try opening a handle. If the handle doesn't open, consider the process as dead. If the handle does open, check if it has an exit code. If not, the process is alive.
