Not really, there is `kill-local-variable'.  But I agree, not big
reason to make it possible to turn it off.

Sounds good, make sure to add to the kill-buffer-hook *locally*,
using org-add-hook (for XEmacs compatibility).

You can also loop over all buffers and find the ones which
are in org-agenda-mode.  This is a bit easier than keeping
track of them.
