Thanks, this might make a difference when caching files. Ports are used
for creating a file name index in the cache, but I'm not certain they
are always taken into account, in all dark corners of Tramp. Will analyze.

However, it would be great if you could reproduce the bug somehow in an
Emacs instance started with

--8<---------------cut here---------------start------------->8---
emacs -Q --eval '(setq tramp-verbose 10)'
--8<---------------cut here---------------end--------------->8---

If the problem happens, pls show the recipe to provoke, and the Tramp
debug buffer.

Best regards, Michael.
