As per discussion with Martin Basti, it was decided that this workaround
will only be applied to the current 4-2 branch, not to the upstream. In
That sounds like a reasonable plan for this issue.

upstream the issue itself will (supposedly) be solved
Except currently it's not, so (IIUIC) you will keep having
nondeterministic failures in master.

I was mostly interested in the general approach that we have to
workarounds -- how do we track them, how do we make sure they don't
stick in tests forever, even after the issue was already properly

I'm not sure if there is a formal process how to work with workarounds.

Usually, we open ticket, push workaround there, and leave ticket opened until
the issue is fixed.
If there is no time to do proper fix and workaround works well we close ticket
and open new ticket in further milestones.

I do not remember if we have a similar issue with test workaround in past.
Can we anyhow utilize "wait_for_dns" knob we added for making DNS tests 

I already do that when records in CI test are created, there is polling.

The first part of oleg's workaround has nothing common with timing issue, only restart of named process will help

The second part, I do not know why there is 1sec delay needed, because presence of signed records was detected in step before, so DNSKEY record must be available, and probably this is caused by named internals, that DNSKEY record is available later than signed records of zone. I don think so that extending testing for all types of DNSSEC records is worth it and 1sec is enough for bind to be ready.
