Thank you - what about the task creation using `Threads.@spawn`? Your original code indicated that there were channels involved.

Can you share your full code? [I still can’t copy and paste it into my REPL](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757) to find out whether it deadlocks on my machine as well.
