Hello! Currently `vminfo''s output looks like this:
#v+
$ vminfo $$
0[0x1000] (prot=0)
0x1000[0x18000] (prot=RX, max_prot=RWX, mem_obj=52)
0x19000[0x1000] (prot=RW, max_prot=RWX, mem_obj=52)
0x1a000[0x1000] (prot=0, max_prot=RWX)
0x1b000[0xfff000] (prot=RWX, mem_obj=53)
0x101a000[0x1000] (prot=RWX, mem_obj=54)
0x101b000[0x1000] (prot=RW, max_prot=RWX, mem_obj=55)

This compares to Linux's `/proc/PID/maps' pseudo file and `pmap' program
as follows:
#v+
$ cat /proc/$$/maps

080ee000-080f3000 rw-p 000a6000 03:05 80383 /bin/bash

Now, the question is: how to use the memory object id (which `vminfo'
internally gets from the `vm_region' call) to trace back the pager /
server providing that memory object and ask it about the file's name that
is backing this region of memory? Is this possible to do?
