You may be right, but your calculations are an order of magnitude off. :)

Maybe you were not really awake yet (look at the Date header!), but if
its 15 errors/KLOC, then 90K lines of code should have 90*15=1350 bugs,
not 9*15=135.

You made the same mistake with BIND.  I do not like those two pieces of
software, but this time you showed that the Sendmail/BIND people are
better than the average programmer.
