That was just a question. I really do neither know the number of
volunteers nor the review process (I found this article just because
it was mentioned on the bug report). But perhaps you can find external

Paul wasn't flamed *for asking questions*, but for not listening to
arguments of other people.

Yes, but this doesn't make Paul's article correct. If he can fix his

the bug report, as well as pointers to external documents); but most
of it is wrong, in particular the whole conclusion.
