The very first thing I said in my very first message on this topic is
that I've been following LKML for a couple of weeks now and following
the VM work. I _know_ there are VM problems. I _know_ there are people
working on the problems. Yet, when I post a specific example, with
_clear and simple_ instructions on how to reproduce a problem I'm
experiencing and an offer to do whatever I can to help fix the problem,
I am told repeatedly, in effect "you need more swap, that's your
problem" (which isn't really even related to the issue I reported) by
names I have come to recognize and respect despite my status as not a
kernel hacker. Why shouldn't I be flabbergasted by that?

huh ... I just don't know how to take that except it seems to uphold
everything I said to which you responded so intensely.
