I stay corrected: thread-join propagates also errors to the calling thread.
I've modified Tramp not to propagate errors to the main thread. In
find-file-noselect, thread-join is wrapped now by with-demoted-errors.

Pushed to the feature/tramp-thread-safe branch. Gemini, could you pls
check whether this works for you as expected?

Best regards, Michael.
