The exec model sounds reasonable to me.

But, I think the filename of the exe is going to have to be in the
checkpoint *already*.  It is mapped by at least one of the VMAs, and
will probably be dumped as a normal file-backed area.  

Now, since arg_start is already set up at exec time, it doesn't seem
unreasonable to have the theoretical fs/binfmt_cr.c set it as well.
