Unfortunately, the logic in binfmt_script and binfmt_misc does +not expect to get restarted. They leave bprm->interp pointing to their +local stack. This means on restart bprm->interp is left pointing into +unused stack memory which can then be copied into the userspace argv +areas. + +After additional study, it seems that both recursion and restart remains +the desirable way to handle exec with scripts, misc, and modules.
