emacs-27 is still looping with that patch:

openat(AT_FDCWD, "/home/rpluim/repos/emacs-27/lisp/net/tramp-archive.elc", O_RDONLY|O_CLOEXEC) = 14
openat(AT_FDCWD, "/home/rpluim/repos/emacs-27/lisp/net/tramp-archive.elc", O_RDONLY|O_CLOEXEC) = 15
openat(AT_FDCWD, "/home/rpluim/repos/emacs-27/lisp/net/tramp-archive.elc", O_RDONLY|O_CLOEXEC) = 16
openat(AT_FDCWD, "/home/rpluim/repos/emacs-27/lisp/net/tramp-archive.elc", O_RDONLY|O_CLOEXEC) = 17
openat(AT_FDCWD, "/home/rpluim/repos/emacs-27/lisp/net/tramp-archive.elc", O_RDONLY|O_CLOEXEC) = 18
openat(AT_FDCWD, "/home/rpluim/repos/emacs-27/lisp/net/tramp-archive.elc", O_RDONLY|O_CLOEXEC) = 14

Iʼve not trapped it reliably in gdb yet. master is the same
