This may take a looong time on a large spool, but it should not...

so you might not have heard the seeking noise. :)
Some intermediate versions ran the chmod themselves upon install, which
caused user complaints from those running larger spools, so I made it
into an instruction shown to the user. The next snapshot will add a note
that this chmod can take a long time to run.
I can imagine some reasons why chmod might hang: a. kernel bug, b. file
system corruption, c. recursive links (might happen once in a while), d.
mandatory lock (requires mount option, rather uncommon).

Revoking read and execute rights for "other" users prevents malicious
users from setting hard links to articles, which would cause texpire to
skip the hardlinked articles, and ultimately fill up your disk.
If only trusted persons have file system access, or if /usr/local/news
is a file system (mount point) in its own right, you can forget about
this issue, as there are either no malicious users per the assumption,
or there cannot be malicious hard links as hard links cannot cross file
(leafnode-1 tracks the seen Message-IDs as it offers spool access
officially, leafnode-2 doesn't, so removing user access to the spool is
the natural fix.)
