This creates a file in $HOME/.lguest/ to directly back the RAM and DMA memory
mappings created by map_zeroed_pages.
I created a test program recently that measured the latency of a
reads/writes to an mmap() file in /dev/shm and in a normal filesystem.
Even after unlinking the underlying file, the write latency was much
better with a mmap()'d file in /dev/shm.
Surely the difference disappears once the pages have been faulted in?
