write-quit-all can hang when multiple files are opened

[antoyo]

Reproduction steps

• Download these two files:
  • https://gist.github.com/antoyo/0a5cf7c2578ee9dbbcd585b84511682a
  • https://gist.github.com/antoyo/2187862df59fe383fddf3b778ed46039
• Open them both using helix gcc_asm gcc_asm2.
• Run the command: :write-quit-all.

You'll notice that the TUI hangs and helix uses 100% CPU.
I let it ran for over 5 minutes.

Environment

• Platform: Linux
• Terminal emulator: Alacritty
• Helix version: helix v0.6.0

~/.cache/helix/helix.log

Nothing relevant

I also noticed that issue.

I believe this was the same problem as #3975. I don't see this behavior anymore; I think it was fixed by #2267
