The only solution to this would be passing some value back to the parent
(who should expect this). In general, there is no way to modify the parent's
environment. I suggest to use either a return value (caught after wait'ing
for the child's death), or a pipe (possibly named in the UNIX domain), or
if a special monitorable action causes the cd inside the child, let the
parent monitor these actions, too, and react in the same way.
