Finally, I have implemented `interrupt-process' for remote
processes. I've committed 296472f5c5 to the Emacs repository. Yegor, do
you have a chance to test Emacs 26.1, whether this works for you?

I've implemented this as advice on `interrupt-process', but this is
discouraged for primitives. Maybe we should spend `interrupt-process' a
hook where Tramp could enter? Or even a file name handler, based on
default-directory of the related process-buffer?

Best regards, Michael.
