generic/084 try to run 'tail' command, tail will use inotify.
There're some limit about the number of inotify. For example
fs.inotify.max_user_instances specifies an upper limit on
the number of inotify instances that can be created per real
user ID.
When I test on a machine with 154 cpu cores, this case run
failed, and hit many warning likes:
+tail: inotify cannot be used, reverting to polling: Too many open files
Because the fs.inotify.max_user_instances is 128, so if we
try to tail 154 files, it will be failed.
So use src/multi_open_unlink to instead of tail will avoid
this problem.
