Thanks for that reminder. I forget how practical that is at times.

I agree with throwing ram and trimming swap space down. On windows they 
want a huge swap so the system can dump. I think the last time I cared 
to spend the time to trouble shoot a windows machine via a dump was over 
12 years ago. Maybe more. Is a lot cheaper and quicker to just start 
rebuilding most of the time.
