Problem Description: 
        Bugid 1095401 - Setup a machine with Unbundled ARM product to allow
        rsh(1) access and use rsh (from this, or from another machine) to 
        execute a command. The command will execute OK, but it will
        leave two processes and a zombie, behind.  The defunct process is 
        the one that executed the command; it is presumably waiting to be 
        reaped by its parent (in.rshd). The in.rshd has vfork'ed
        the keyenvoy and these two processes are deadlocked; in.rshd is 
        waiting for input from keyenvoy; keyenvoy is waiting for input 
        from in.rshd.
