Hello everyone!

Yesterday I got a strange set of test errors, probably somehow related to
that patch.
It happened on changed master branch (based
on d96d1d5152f30d15678e08e75b42756101b7cab6) but I don't think my changes
were affecting it.

My setup is a little bit tricky: Windows 11 run WSL2 with Ubuntu, meson.

So, `recovery ` suite started failing on:

1) at /src/test/recovery/t/019_replslot_limit.pl line 530.
2) at /src/test/recovery/t/040_standby_failover_slots_sync.pl line 198.

It was failing almost every run, one test or another. I was lurking around
for about 10 min, and..... it just stopped failing. And I can't reproduce
it anymore.

But I have logs of two fails. I am not sure if it is helpful, but decided
to mail them here just in case.

Best regards,
Mikhail.
