If you can implement the interface that takes many objects and ranges from
each, please do that.  The reason to want this is so that we can use it to
compose proxy memory objects that span adjacent memory objects of logically
contiguous underlying objects like files and disks.  That lets us use the
new io_map interface that I prefer, and keep the mmap atomic to the user,
for 64-bit files/devices.  (Remember the RPCs were all updated except for
io_map, which is still constrained to the first 4G of the file.)
