Well, I've just tried it now and it works

#!/usr/bin/perl
use strict;
use warnings;
use CGI;

my $q = CGI->new;
print $q->header;
if (my $pid = fork ) {
    print "Hello, world - PID $pid\n";
    exit;
}else{
    close STDOUT;
    close STDERR;
    close STDIN;
    sleep(20);
    exit;
}

I have verified that the script is still running: ps auxx | grep perl
