One additional complication you might want is to make sure the script isn't in a death spiral.

my $lockfile = $destDir."loadqueue.lck";
my $failcount = 0;
while ($failcount < 10000)
{
    while (!open my $fhLock, ">", $lockfile)
    {
        print "Failed to open $lockfile: $!";
        $failcount++;
    sleep(3);       ### Changed from 3000 to 3 (parameter is seconds, 
+not milliseconds!)
    }
    last;
}

Edit: Changed sleep(3000)to sleep(3)(stupid human tricks when switching back and forth between languages)
