But now, you really don't know that, do you? People are fooling
themselves when you think that the blackhats don't already know about
issues like this. We don't know what they know, so adopting a
head-in-the-sand mentality only really inhibits the user base.

OK, that's fair. But do you think they need to hold off entirely up
until the point they have a patch pushed to *.dl.sf.net?

Listen, nobody expects Tokio to be perfect. If people hadn't started
making some noise most of us wouldn't know there is a pending patch.
Yet we still haven't broken any code-of-silence, nor have we aided any

Agreed. I would only add that we need to encourage them to do this as
part of their fix-test-release process. I can't recall them ever giving
advance notice or recommendations. The only ones I recall are when a
user has publicly raised the issue and one of the developers have come
forward and recommended tweaks to private.py and/or Cleanse.py.

It's a good thing because it keeps your users in-the-know. Again,
nobody is expecting perfection, just info. If you don't know how long
it will take, don't say 7 days. Just say "I don't know, we are working
on it". At least then users will know something is up. After that if 2
weeks go by without a patch users can start some Q&A to possibly keep

I think you don't understand project management and process tracking.
;-) Again, nobody is screaming for miracles, just some info. Don't
keep everyone in the dark just because you think nobody knows about this
or that yet.
