    Subjectfork problems (zombie children)
    What am I doing wrong?  The following program:

    #include <signal.h>
    #include <sys/wait.h>
    main(){
    for(;;) {
    if( !fork() ) {
    exit(0); /* child, exit immediately */
    }
    sleep(1);
    }
    }

    when run with PID=8704 creates children that stay undead until the parent
    process terminates, e.g. from "ps -x":

    8704 v14 8 0:00 ./forktest
    8705 v14 8 0:00 (forktest) Z 8704
    8707 v14 8 0:00 (forktest) Z 8704
    8708 v14 8 0:00 (forktest) Z 8704
    8710 v14 8 0:00 (forktest) Z 8704
    8712 v14 8 0:00 (forktest) Z 8704
    8714 v14 8 0:00 (forktest) Z 8704
    8716 v14 8 0:00 (forktest) Z 8704
    8717 v14 8 0:00 (forktest) Z 8704

    I ran out of virtual memory on my 32Mb machine on a different app (lynx)
    after lots of these were created.
