the Linux process for generating many rare flaws

I read "it isn't, of course" as responding to my question about how black-hat scrutiny was
something unique to Linux's development process.  These threads get a little spread out...

I would still be curious to hear your response to my original post, because a priori I don't
see why any one of Linux/Solaris/OpenBSD's models should be better.  (Actually, I don't have a
lot of confidence in OpenBSD myself, because I've gotten the impression that in general it's
buggier -- probably just due to lack of manpower, and prioritizing security features
proportionately higher than non-security testing and bugfixes.  And I don't like non-security
bugs much better than security bugs.)
