Well, there you go. That will then potentially create 407 simultaneous
connections. If you want to limit the amount of parallellism, you limit the
rate you add new handles. You can for example use the counter that
curl_multi_perform() provides to know how many active transfers there are, to
keep your quota where you want it to be.
