Yeah, it's going to be difficult

I got a directory info extraction thing going, but this stuff might be pretty hard. The reason I'd like to use Haskell is that it makes the drawing code easy, but I don't really have an idea on how to do the multithreaded traversal cache. In C#, it's somewhat the reverse. Maybe I should try rewriting the C# drawing code now to fulfill my daily quota of head-wall interaction.
