Problems with FFS and directories of over 1000 entries....

I see no issues on my systems, either 4.x or 5.x, with up to 10k files
in a directory.  Enabling the UFS_DIRHASH kernel option (available in
4.4 and later) will greatly speed up access to large directories, at
the cost of a little memory (adjustable via sysctl).
