No company should have to face that sort of problem, any problem that
severe should be easily found in preproduction testing. Linux'es low-cruft
level usually causes pretty consistent and testable behavior, once it
works it tends to keep working. Additionally, any problem so severe and
repeatable to cause such problems should be easily fixed with or without a

I've seen an example of a fast bugfix from a company with a wonderful
in-kernel debugger.

When the teardrop became common, Microsoft used their wonderful debugger
to find a great point to insert a 'if packet looks like this' filter. They
didn't fix the problem in their initial patch. They inserted a fast
non-fix, the kind of behavior encouraged by debuggers (fix the symptom, not
the problem). Just a few days later, they were being crashed again by a
minor variant of the same bug.

Linux on the other hand, had a true fix and were not subject to the
revised attack. (Incidentally, Linux's true fix came out before MS's quick

Quick fixes bring about quick cruft. The 'expense' of maintain code grows
exponentially with it's cruft level. A 'slower' fix today will likely
improve long term sustainablity.

Finally, who says that acceptance by 'IT managers and CTOs' is actually a
measure of 'quality' that anyone here finds interesting or acceptable? The
very fact that many 'IT managers and CTOs' find NT acceptable speaks
volumes to counter the credibility of that as a useful product metric.
