10,000 IP addresses, or domain names? We only need to block the  
webservers.
btw, how does the library proxy handle this much? I think tor can do  
regex matching on the ip/hosts.

I think the best thing is to use a nice tree for all directory  
lookups. Something tells me tor uses a slow linear search through the  
file if it's not scaling O(lg n).
