What I find odd is that there is so much intense paging supposedly just to free the address space. I'm curious why it pages in anything (much) just to free it all up. :-) A kill -9 doesn't cause any execution, so it shouldn't be the result of signal handlers firing up and paging data in etc. Of course, if the paging is a result of trying to free up space for temporary VM tables etc, then maybe that's different - but it still seems awfully big.
