A good name for this syscall has been elusive :)  George has always
wanted to call it "mapme(2)" but that seemed a bit odd.  I agree that
mmapfd(2) doesn't seem like it differentiates itself from mmap(2)
enough.  mmapv(2) does seem to follow readv(2) more closely so maybe
that will be a better name.  I'm open for other suggestions as well.

Thanks,
