Sergei Golubchik 8bb8820df2 MDEV-22949 perfschema.memory_aggregate_no_a_no_u fails sporadically in buildbot with wrong result ...

perfschema aggregation, like SHOW STATUS, is only statistically correct.
It doesn't use atomics for performance reasons and might miss individual
increments, particularly when two connections are disconnecting at the
same time.

To have stable results tests should avoid doing it.
