Then find some friendly reviewers. It doesn't have to be a "throw crap
over the wall and see what flys back review". If it has dicey locking
and race issues, then the security and reliability of the whole system
is effected.

And therefore their driver gets broken regularly. The modified by others
is almost always for small compatibility stuff.

If it is important enough for Ubuntu to ship, then it probably is important
enough to get out of the closet.

Which is true, unfortunately, unless they read about it on a regular basis,
most people will plead ignorance.

I don't mean to play shoot the messenger, you are helping a lot by doing this
I wish every distro did.
