X The cool thing about doing it this way is that we gain X persistence of memory even across reboots. I wonder if you X could memory map a file that's mounted via NFS? X

X Like the shared memory tutorial, this one is also very basic and X primitive. I'm assuming you've read that one, so I'll just hit X the high points this time through..
