  This is skirting the edge of my understanding, but my understanding
is that the virtual size is the total of all pages mapped into a
process's virtual address space.  That can include:

- pages in main memory ("RAM")
- pages swapped out to disk
- mmap'ed files
- shared libraries
- IPC shared memory
- kernel resources
- hardware I/O

  So, basically: Here there be dragons.  ;-)
