We implement AT_UID and AT_GID process auxillary vector (procstat -x) elements so at least userland library (such as glibc) has a possibility to enter "secure mode" on startup. Not sure if there is anything we can do more (except for disabling the feature altogether) to tell userland to be careful. //Marcin
