 * with respect to managing their respective shadow contexts. Cobalt
 * should drop the child's shadow upon detecting exec(), then create
 * another one for the emerging process's main() thread as usual.
 *
 * We don't have to do much beyond firing such sequence fo testing: if
 * Cobalt messes up, the kernel will certainly crash.
