zombie process
     
         or "defunct process" a unix process
        that has terminated either because it has been killed by a
        signal or because it has called exit and whose parent
        process has not yet received notification of its termination
        by executing some form of the wait system call.
     
        a zombie process exists solely as a process table entry and
        consumes no other resources.  this entry is retained to hold
        the child's exit status until the parent process wants to
        retrieve it.  the parent can also be notified asynchronously
        via a signal of the child's termination.
     
        zombie processes can be seen in "ps" listings occasionally
        with a status "z" in some versions.
     
        compare orphan process.
