i think we mostly agree.  i'm a little sick of trying to read code with
gobs of recovery goo that may or may not ever get executed.
who knows?

on the other hand, you're right.  if there's a way to kill the kernel by 
running it out of memory, then that should be fixed, if possible.
no questions. 

it would be better for xcpu to start lining up processes for the 
firing squad until sufficient memory is available.
