Comment(by peter@…):

 What kind of queries are hitting SQLite here? Let's talk tomorrow.

 [wiki:Meetings/Minutes/2010-01-28] mentions looping over many thousand
 zones in order to detect changes. I would strongly recommend using
 operating system notification instead; anything based on stat() just will
 not scale.

 Linux has had Inotify for a long time and it works very well, the more
 recent fnotify arguably has a friendlier API but may be less widespread.
 Systems other than Linux must also offer a similar notification service. I
 don't think polling the answer.
