I've reopened it, until we get an agreement.

A general support for polling in filenotify.el is not foreseen, too much
effort. But I believe, in the auto-revert case Emacs works already this
way. When file-notify-add-watch returns nil, auto-revert falls back to
polling (to be tested, I'll I add a test).

Would be possible, yes. I would prefer to set the limit to a system
related value. Does there exist a portable way to detect, how many file
descriptors / processes Emacs is able to consume?

Done, see above. I don't know whether we want to increase the resources
silently for Emacs.
