Then I added 20,000 more: 1 GB. All queues were exclusive. After shutting down
the process used to create them, VM RAM consumption quickly went up to ~ 2 GB
then decreased to ~50 MB I had from the start.

So regardless of the absolute value you get at one point, the number can
still vary over time and you need to account for that.
