You created a new implementation, right? No copying of the existing code?

So what flags *are* you using?

Depending on the flags set, you may need to free the cache before trying to
reload it. Of course, if you know what interface was added/removed, you could
add/remove it directly to the container instead of reloading the cache.

Also note that ifIndexes should not get renumbered as rows are
inserted/deleted.
