    That's interesting, but if it's unsafe to 'require threads' directly, seems that this approach is just doing the same thing indirectly and would suffer the same kind of problem. If the problem is just that you must be sure that threads is there at compile time maybe something like this would work: 
    BEGIN {
    if ($] > 5.008008) {
        require threads;
    }
}
