IT's not so much that it's "wrong" - it's just ignored.
What if you are designing for a system that won't ever have a swapfile/pagefile? What if your application is designed so your working set fits in ram? Then you can use other methods and not worry about fighting as much with the VM.
I love this article - because a reverse proxy is a great example of this.
(You want to cache transitory data to disk - You plan to roll your own caching system to keep data locally so you don't go back and query source nodes. You want some legroom to work with working-sets that may be larger than your physical ram, and you may want that ram cache to survive reboots intact.
So memory-map the file and let the OS take care of the rest - makes sense to me.
EDIT: What I meant to say was "It's not so much not fighting with the VM - it's realizing that the VM is more than something to ignore, and that it can be used to your large advantage by treating it like what it really is - a system that deals with shuttling data between different levels of storage (disk/ram).
