I've had trouble before when somebody for some odd reason decided to recursively suck my entire website in one go.

Yeah, I thought it was something like that or a badly written spider until I realized that all the source IP addresses were different. This has to be either the worlds least impressive DDOS attack or some virus. I think that shoots down the annonymizer theory as well (all the source IPs would point to the annonymizer proxy IP). Whatever it is it is still happening
