Just wanted to report that I've been using this branch for the last few days and it works perfectly. Thanks a lot for your work on julia-snail @gcv !

I'm not entirely sure what's going on, but I am ocassionally experiencing something that I think is related to julia-snail where my entire window manager locks down and I'm completely unable to do anything without rebooting. Can't even move the mouse.

This has happened around 4 times to me total, and only ever when I was on this branch of julia-snail, and editing julia text, so I suspect it's some bad interaction with emacs async stuff. I disabled julia-snail and haven't had the problem reappear yet.

Sorry I can't give a better error description or a reproducer yet, but I'll continue to monitor this and see if I can figure anything out. I'm on Fedora 41, KDE Plast 6.3.2, Emacs 29.4 (build 1, x86_64-redhat-linux-gnu, GTK+ Version
3.24.43, cairo version 1.18.2) of 2025-01-03

I've definitely noticed my Emacs sessions briefly freeze up while a synchronous Snail request hits JuliaSyntax, but so far have been blaming TTFX issues. Though it would be weird for this to happen to something presumably precompiled into the shipping Julia image.

That it locks up your window manager to the point of needing a reboot is completely wild, though. Can you ssh into the box and see if it's the emacs or julia process running amok? If it's a hard kernel crash, that's even worse.
