Slow filenotify-tests

Hi,

I've run filenotify-tests today on a GNU/Linux machine, and found many
of the remote tests to be too slow:

   passed   2/28  file-notify-test00-availability-remote (1.716848 sec)
   passed   4/28  file-notify-test01-add-watch-remote (1.238100 sec)
   passed   6/28  file-notify-test02-rm-watch-remote (17.882603 sec)
   passed   8/28  file-notify-test03-events-remote (166.341733 sec)
   passed  10/28  file-notify-test04-autorevert-remote (19.500194 sec)
   passed  12/28  file-notify-test05-file-validity-remote (51.576937 sec)
   passed  16/28  file-notify-test07-many-events-remote (324.932327 sec)
   passed  18/28  file-notify-test08-backup-remote (30.162599 sec)
   passed  20/28  file-notify-test09-watched-file-in-watched-dir-remote (127.011329 sec)
   passed  22/28  file-notify-test10-move-file-to-another-watched-dir-remote (43.803668 sec)
   passed  26/28  file-notify-test12-symlinks-remote (44.753902 sec)
   passed  28/28  file-notify-test12-unmount-remote (14.924635 sec)

This is with gio library, in case it matters.

Shouldn't the remote tests be marked as "expensive"?
