Heh -- I bet you didn't count the ports tree. :-) When I last counted (a few months ago), the repository as a whole had 48,500 files in 12,900 directories, totaling 564 MB of space. I'm sure it has grown since then (egcs plus the ports team's usual 8000 ports per month). The vast majority of directories are in the ports tree, and they're very small. I don't know whether that makes a difference or not with regard to the VMIO fix. If I can figure out a way to do a realistic test here locally, I'll try it out.
