PATCH: couch_stats_aggregator should use queue instead of list
--------------------------------------------------------------

                 Key: COUCHDB-797
                 URL: https://issues.apache.org/jira/browse/COUCHDB-797
             Project: CouchDB
          Issue Type: Improvement
          Components: Database Core
            Reporter: Sean Bartell
            Priority: Minor
         Attachments: 0001-stats-use-queue-instead-of-list-for-speed.patch

couch_stats_aggregator uses a list to store samples, but many times per second adds a value
to the front or removes one from the end. This patch makes it use a queue instead. Statistics
take up little CPU time, but there's a noticeable improvement when CouchDB is idle.
