bug#70760: 29.3.50; core dumps when copy in other apps

[Kun Liu]

Just a quick update: I went through my .emacs line by line and was able to find the culprit.

After I commented out "(follow-mode t)", Emacs has been running fine for a few hours now.

It appears the combination of org-mode, follow-mode in Emacs 27-30 running in a Debian 11/12 VM in VirtualBox 6/7 on a Windows 11 host, and a copy operation on the host, sometimes causes problems.

Thank you, Eli and Michael, for your help. I really appreciate it.

I've tried various combinations of Debian11/12, Emacs 27/28/29/30, native-compilation yes/no. This behavior seems to be always present.

On the other hand, based on all the tests I have done, it appears that this issue happens when org-mode is loaded. I will run more tests and report back if I see it happen without org-mode.

Which file descriptors do we listen to, apart of sub-processes and
inotify?
