Ugh. This patch is a forward-port of leafnode-1's noread, let me know if
it works for you (please use the latest version from
http://home.pages.de/~mandree/leafnode/beta/ as the basis) - save this
mail to /tmp/noread.patch, unpack the leafnode source, run

patch -p0 </tmp/noread.patch

then compile and install as usual. Let me know if this works or if you
have concerns.
