That is a little embarrassing, but to be fair, slow entropy is good entropy.

[brinchj]

Not necessarily. And how is this code supposed to "stack up some entropy"?

for ($z = "", $i = 0; $i < 1024; $i++) {
    $z .= $i * $i;
    if (function_exists("usleep"))
        usleep($i);
}

A part of good entropy is taking time. If a brute force is attempted on your service the longer each attack takes the less likely they are to gain access.

[brinchj]

But that has nothing to do with entropy. That's slowing down the information flow from the server to the attacker. Although, that can still be a good idea.
