ps/top doesn't show the process on a smp kernel ;)

[khandelw]

Hello,
    This is the simple program that I tried on a - 2.4.20-30.9smp #1 SMP Wed Feb
4 20:36:46 EST 2004 i686 i686 i386 GNU/Linux (kernel) machine.

The ps command doesn't show me the process.  /proc/ shows that these process are
present in the system. When I uncomment the call getpid(). Then it shows me the
process. I am not able to understand this behavior and I hope this is the right
place to post this question/bug.

int main()
{
    int i = 3;
    pid_t pid, pidarr[3];

    for(i = 0; i < 3;i ++) {
        if ( (pid = fork()) == 0) {
            while(1){
                /* getpid(); */
            }
        }
        pidarr[i] = pid;
    }
    for(i = 0; i < 3;i ++) {
        waitpid(pidarr[i], NULL, 0);
    }
    return 0;
}
