Hi Ihor,

Thanks for your email. Sure, glad to share the backtrace with you.

This is how the issue can be reproduced on my system.

- Enable debug, `toggle-debug-on-quit'
- Open a remote file, `(find-file "/ssh:<remote-machine>:~/test.org")'
- Bring the remote machine offline
- Try to close the remote file, `kill-buffer'
- The system hangs for a while as it tries to reach the remote machine
- Quitting (`keyboard-quit') produces the following backtrace

#+begin_export ascii

Glad to share other info if helpful.

Thanks, cheers, Fabio.
