It's getting there. The 'issue' is that the best way to fix it (maybe
2.4.20-pre1 even) is to backport the 2.5 zlib which doesn't have this
problem and removes most of the copies of zlib from the kernel. If it's
not really a problem now, why fix it? (Tho it should be a safe fix now
that Paul has produced a patch which doesn't suffer from random oopses
or other problems).
