code: def execute(path, arguments):
      
      pid = os.fork()
      if pid == 0:
          try:
              os.execv(path, arguments)
          finally:
              sys.exit(1)  # In case path is not executable
      else:
          try:
              # Wait for subprocess to finish
              os.waitpid(pid, NORMAL_PIDWAIT)
          except OSError:
              pass  # The subprocess was already finish
          return
docs: Wrapper around execv():
  
      * fork()s before exec()ing (in order to run the command in a subprocess)
      * wait for the subprocess to finish before returning (blocks the parent
        process)
  
      This is **hyper** simplistic. This *does not* handle **many** edge cases.
  
      *DO NOT DO THIS*: subprocess.check_call() does it better, and handle edge
      cases.
