Idle couchbase eating CPU (couchbase 6.5.0, or bleeding edge git)

I’m running couchbase 6.5.0++ from git, community edition.
It’s a single standalone node, data only, no index, no search, no query.
I loaded the gamesim-sample bucket.
No users, no gui pages open.

When I look at the CPU usage, I notice memcached using between 1 and 20% of CPU, and beam.smp using between 0 and 5% CPU.
Then, stracing beam.smp for a period of 100 seconds, shows that it is generating queries to (on average):
/pools/default/remoteClusters every 5 seconds
/pools/default/replicationInfos every 5 seconds
/pools/default/replications every 5 seconds
/stats/buckets/gamesim-sample once every second

The one I’m most concerned about is the /stats/buckets/gamesim-sample query; once every second seems excessive. Why is it doing that? Can I eliminate that? Or, if not, can I lower the frequency?
When creating more buckets, I notice it starts querying every bucket stat once per second. I’m guessing that that is what is causing the senseless CPU load on memcached.

Raw list of requests from beam.smp:
