The quoted part of my answer applies to this. The answer is "no" (for now).
Note that "exec" time is a bad point to migrate, since it implies a lot of
inherited fork() environment. The POSIX spawn*() concept is much
friendlier, since the new environment has a much more structured set of
initial values.
