(to neni z moji hlavy, ale z Internetworking with TCP/IP, Client-Server

==========
Unix sends a signal to parent whenever child process exits. The child
process remains in
zombie state until parent executes wait3 system call.

/* in parent init section*/
signal(SIGCHLD,killer);


int killer()
{
     union wait status;
     while( 0 <= wait3(&status,WNOHANG,(struct rusage *)0) );
}
