   2    the vmap struct is used to describe the virtual address space of
   3    the target we are manipulating.  The first entry is always the "exec"
   4    file.  Subsequent entries correspond to other objects that are
   5    mapped into the address space of a process created from the "exec" file.
   6    These are either in response to exec()ing the file, in which case all
   7    shared libraries are loaded, or a "load" system call, followed by the
   8    user's issuance of a "load" command. */
