Ob-Julia extension crashes Emacs on MacOS
When executing a code block Emacs freezes and gives the following call stack:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSWindow geometry should only be modified on the main thread!'
*** First throw call stack:

libc++abi: terminating due to uncaught exception of type NSException
Tested with homebrew [email protected] with minimal julia-snail config:
(use-package julia-snail
:config
(setq julia-snail-extensions '(repl-history formatter ob-julia))
(add-to-list 'display-buffer-alist
'("\\*julia" (display-buffer-reuse-window display-buffer-same-window))))
Not much we can do about this type of crash from the Snail side. Does this error occur if you use the same build's terminal Emacs (/Applications/Emacs.app/Contents/MacOS/Emacs -nw or bin/emacs -nw or something along those lines)? What about using a different distribution of Emacs, like the Mac port (https://github.com/railwaycat/homebrew-emacsmacport)?
The issue is related to the julia-snail/ob-julia-interaction-mode. Specifically with the advice around Ctrl-C Ctrl-C. The way I understand it is that this facilitates async execution of code blocks. Removing the advice around org-ctrl-c-ctrl-c makes the execution synchronous, but it ends up working.
The same issues appear with Macports Emacs and Emacs installed with Homebrew.
