I separated what I had so far into a separate class, so the main program will only contain code needed to turn the whole thing into a server. If I'm going to use C++, I might as well do it right.

I'm starting to get a little concerned about the file system. I've got close to 11,000 blogs indexed, which means I have around 33k files in one directory, and I'm a little nervous about going over that magical 32,768 threshold (for those who don't know int types often only go up to 32,768). I don't know if it's related, but linkdex took for ever to read in all the links, and CPU utilization stayed at <5% (which indicates that something else, like disk access, is preventing it from maximizng CPU usage). I think the solution is to split them up into a hierarchical structure... shouldn't be hard to do, but I might have to modify some of the existing code.
