Thanks for the congrats. You're welcome. And indeed, I only reported,
the devs did the actual work.

The logs start looking weird, to me at least:

%CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
 5.1  2.2 1706748 87208 ?       Ssl  Apr17  41:00 /usr/bin/myt
 5.2  2.2 1706748 86804 ?       Ssl  Apr17 116:20 /usr/bin/myt
 5.3  2.5 1706748 95612 ?       Ssl  Apr17 198:05 /usr/bin/myt
 5.4  2.6 1706748 102480 ?      Ssl  Apr17 278:57 /usr/bin/myt
 5.4  2.8 1706748 106516 ?      Ssl  Apr17 358:35 /usr/bin/myt
 5.4  2.6 1627816 100416 ?      Ssl  Apr17 438:03 /usr/bin/myt

Yes, both VSZ *and* RSS go down at least once. (!)
It's only a few days of logging with 0.23-fixes but it shows us
different phenomena.
It's not giving reason for concern, just wanting to understand what's
happening...

Kind regards,
Udo
