Ok, tried with, ehm, Emacs. Same problem when copy/pasting to the clipboard.
NeoVim also produces those messages when copy/pasting. So, it appears to be
clipboard-related. That's why reattach-to-user-namespace fixes it. OS X's Vim
has -clipboard, so no problem. Not sure why they are triggered at startup or
when opening netrw, though.

Hence, I will stick with reattach-to-user-namespace, as previously suggested.

Sorry for the noise.
