Linux doesn't (as of 1.2.X) really have a merged vm/buffer cache.  It does
apparently have a dynamically sized vm/buffer cache.  FreeBSD does have a true
merged VM/buffer cache.  When you map a file on FreeBSD you *really* have
true read/write access and modify the buffers directly.  (I really don't know,
but does Linux give true read/write access with full coherency with read/write
system calls now?)
