 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.
