I'm not trying to troll here; I suppose I'm just coming from a different 
background.  I'll try to adjust my tone.

I'm all for allowing people to shoot themselves in the foot.  That doesn't
mean that it is OK for a single userspace thread to mess up a 64-way box.

Isn't this what the kernel attempts to do in many other places?  What else
could possibly be the point of sending SIGSEGV and causing applications
to dump core when they make a mistake referencing memory?  Isn't it the
kernel's job to protect one application from another? 

I see what you're saying about the swap daemon.  How about if I make my
statement less black and white.  Some kernel threads should always have 
priority over userspace.  

I believe the mindset required for a home system that is doing audio recordings
is different than the one for enterprise-level systems.  How do we unify
the two?
