Do you use Firefox, Seth? This sounds like the sort of thing that could be reduced by tweaking some of the about:config settings that centre around network connections, pipelining, etc. There is one, for instance, that lets the browser get on with making its next requests without having to wait for a response to the previous requests. I'm not an expert in the about:config stuff, but I've had good results from recent tweaking.
I'm getting this with E7 so it's not an FireFox problem... Yesterday it did stop me froma accessing the forums, today it isn't stopping the flow while I'm nevigating around but it is permently saying waiting for smarttargeting.com in the bottom left hand corner of my browser!
I had to look that up to find out what it is, but if you mean Remove It Permanently, that seems to be a content blocker a bit like AdBlock but aimed at any website content. So no, I don't see how that would work. Going by Seth Haniel's description, it's a case of waiting around for something (probably a response) to occur.
