Dear Monks & others,

I don't understand what happens in the script below. Why does the output get jumbled as soon as I remove the comment before my $processes = `ps au`? I would have expected everything inside the child process to run in order, but it looks like the part between the backticks is running asynchronically or something???

for (1..3) {
    my $fork_pid = fork();

    if (! $fork_pid) {
        print "hello" . "\t";
#        my $processes = `ps au`;
        print "world" . "\n";
        exit 0;
    } 
}

This is part of a much larger script in which I need to extract some information from 'ps au' to be used in the script.
