// For each tag we wish to load, we need to determine if it exists at the current
// location. The natural way to do this would be to call s->hasTag( tag ), but that
// actually has pretty poor performance when calling hasTag() for many tags. So
// we load all the local tags with readTags(), and then for each of them test to see
// if they exist in the list of tags we wish to load. We test the local tags against
// the tags because we're in control of the tags and can sort them beforehand for faster
// searching, whereas the localTags just come as-is. Using binary search over linear
// search isn't actually that big a win for a typical number of tags, simply because
// InternedString equality tests are so quick, but there's a very slight benefit, which
// should be more apparent should anyone create a very large number of tags at some point.
