'tail -F' will also notice a file being unlinked and recreated.
You don't want this to be the default behaviour as it is expensive.

Since tail only processes a single file at a time, tail -f on multple
files just doesn't make sense.
If you want the merged output from many files just run multiple copies
of tail -f in the background....
