Why so long for "Ignoring" /Library?

[macmath]

Hello. First of all, thank you so much for SuperDuper!

I've searched here for similar issues and haven't found one quite like this, so I'm going to bother you.

I ran a "Copy Different files..." on a few directories in the home directory. I believe I had it set correctly because it did exactly what I asked. I watched the log, and it was very fast except for with /Library. Below is an excerpt of that log. The whole task took 43 minutes, but for some reason /Library took 32 of those minutes, even though it was completely skipped. I know that it sorts through the files anyway, but /Developer is somewhat larger than /Library and took only a little over a minute.

I've read here about the 'floating file' issue, and there are some files in /Library which belong to a user besides root, but would that matter when the files are to be skipped?

Thank you very much for your time.
Ed
