The title is inaccurate. It should say, "the linux swap insanity problem" because this is entirely related to the linux kernel. It just happens to affect MySQL and similar workloads, but it is not MySQL's fault. It doesn't behave that way on other platforms either.
I agree with you on a purely technical basis, however, this article was written for the MySQL community, was tested (only) on MySQL, and has primarily affected my only on MySQL systems, which I (and the others referenced in the article) primarily run on Linux.
Thats a very good point, these types of problems exist to some extent on other OSes but this case seems pretty specific to Linux. I suspect testing on Solaris/FreeBSD would show better results in this area.

Pretty hard to make you happy, eh?
