02210_processors_profile_log: is it related? looks not very related

It is not very flaky in upstream:

Looks unrelated. Test is very strange, relays in timer precision
https://github.com/ClickHouse/ClickHouse/blob/master/tests/queries/0_stateless/02210_processors_profile_log.sql#L19
an looks like in reality it is not so precision, 999992 is a little bit less than 1e6.
