A note about the context of this particular comment- something like torrentzip takes ages to scan through many files, even if they are already torrentzip'd (skipped files). I suspect that most of that slowdown is due to I/O (they print out a message to stdout and to a log file for every file!), and I'd like to look at the source to see if it can be sped up. Just curious if you had some special tricks...
