I've traced the /lib/modules entries to a bug in unionfs: modprobe opens the kernel modules O_RDWR in order that it can take out a write lock (but it does not actually copy them), and when it close()s them unionfs copies-up an entry to the copy-on-write filesystem, even though that isn't necessary. I'm reporting this to the unionfs mailing list now.
