If someone wants to come up with a replacement function that avoids the post
counts and caches the results, then you're welcome to submit it to Trac.

The latest example would run a query on every page load -- nay, function
call -- on a table that can get very large (and isn't indexed well for this
query). If you're going to have a $num argument, that should be a LIMIT, to
prevent you from querying 70,000 rows then chopping off 69,990.

Personally, I think this is best solved on a per-installation level, which
is often the case when considering how to implement scalable functions and
features in multisite.
