How quickly are you doing this? With prefork a new process is created
for each client, when doing a bench this *can* make it seem like you are
creating an abnormal amount of processes because the queue is filling up
and the KA is either too low or too high (rarely too high but I've seen
it spawn incorrectly with a high KA.) What I am saying is, are you sure
they aren't /dying/ or /defunct/?
