Can anyone tell me how it works? Or could anyone recommend an efficient method for determining when a file in a given directory or any of its subdirectories changes, for a potentially large number of subdirectories?

I think you can receive notifications on vnode operations using the kauth API, which is new in Tiger. I just searched developer.apple.com for "kauth" and didn't turn up much, but there looks to be some meat in sys/kauth.h. Therefore, given that the mds process detects whenever any file on the entire filesystem is written, it seems doubtful that it uses kqueue. This email sent to site_archiver@lists.apple.com
