putting list in "sleep mode"

[Thien-Thi Nguyen]

I admin bug-guile-sdl for GNU Guile-SDL, which hasn't had a
release in a while, so i'd like to put the list into some kind
of "sleep mode" until the next release.  I see in the mailman
2.1.21 documentation (in the source tarball) an empty section:

 6. Deleting the Mailing List

and figure that's related to GNU policy of not deleting mailing
lists (a policy i support).

So, what's the recommended way to put the list in "sleep mode"
for the time being?  Absent a global "disable everything" config
item, i suppose a sleep mode could be effected by:

 - not advertizing the list (‘advertised’ false)

 - limiting new subs: (‘subscribe_policy’ "Require approval",
   then "manually" denying approval -- is there a cleaner way?)

 - some kind of automatic message for posts, along the lines:
   "This mailing list is in sleep mode; your post was discarded.
    Stay tuned for an announcement of the next release,
    at which time the list will return to normal operation."

I suppose the last has to do w/ auto-response but the docs say:

 2.11 The Auto-responder Category

(another empty section).  I suppose i can read the source, but
hope someone here can give me some pointers, to save time.
Towards that end (to save time for the next j.r.list-admin), i'd
be happy to contribute my findings to the mailman documentation
(specifically these two empty sections).
