For some of the issues. A big problem is that if a very popular page
occurs at the end of the month (or after the 500k has been reached), it
doesn't show up as a popular page. A problem this does not resolve is
looking for a specific UR, for example, that may or may not be popular,
but is still important. For example, I want to find all URLs that have a
certain s.prop value that is incorrect. I can't find these now as they
are typically in the uniques exceeded bucket.
