If you deal with the repos the kind of size I'm dealing with, it's all
worth it. A lot of time, many of the subdirectory are of multi-hundred
MB's, where some files can range up to 30MB each. Right now, I have to
play it really carefully when I check in these files and directories,
because a simple rename can cause me a lot of diskspace. And no,
diskspaces are not cheap for us.
