Hmm... Either the patch wasn't enough, or it was broken again.
On v2.6.31-rc4, I get this:

  # echo 10 >/proc/sys/fs/inotify/max_user_watches
  # inotifywatch -r /usr/lib # generate watches up to the limit
  Establishing watches...
  Failed to watch /bin; upper limit on inotify watches reached!
  Please increase the amount of inotify watches allowed per user via
`/proc/sys/fs/inotify/max_user_watches'.
  # inotifywatch /bin/true # just one watch for just one file

AFAIU, the second inotifywatch should work, and the watches of the first,
failed, run must be cleared.
