This can happen if you edit *large* files, and the contents of these
files appears temporarily in that internal buffer. Mostly, people
don't see it because the files are not so huge. Your "/etc/hosts"
shouldn't be so large either; I don't know why it happens to *you*.

Very inconvenient, indeed. I've added a patch to Tramp that the buffer
local variable `buffer-undo-list' of that buffer is set to t, which is
sufficient because there's nothing to be inspected later on.

Will be available in Emacs CVS with next Tramp sync.
