It might be helpful to know that my 2 GB Pi4 has "zram.service"
installed as a swap. With no special adjustments for swappiness.
Perhaps that is one of the reasons for the HUP timing problem.
This may make it easier to reproduce the behavior on other computers.
Today I will try to remove the "delaycompress" as described in the posts
and reboot.
