Err, no, this does not make sense: if data is to be casted into
vm_map_copy, it's not a string, it's some structure with pointers etc.,
you can't expect it to look like a string.

Read about inband data in the mig manual, to understand what is
happening with the vm_map_copy_t copy = (vm_map_copy_t) data; cast.
