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