How to kill Zombie process?

[Chris Gonnerman]

You need os.wait() or an equivalent.  Unixoid OS's will keep a process in the process
table to retain it's return status until you retrieve it with the wait(2) syscall.

    When I use ret=os.fork(),it will create a parent process and child process,when child process exists,it will creaet a Zombie process,How to kill it in parent's process? For example:

  udpSerSock=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
  while 1:
    message=recvfrom(BUFSIZ)
    ret=os.fork()
    if ret==0:
       udpSerSock.close()
       ip=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
       #something deal
       ....
       ip.close() 
       break

  #ps -a
  I will find a Zombie process
