1- setuid/setgid must effect process
2  + test syscalls (getuid) afterwards
3  + test core file content
4
5  + use UID/GID in access(2), chmod(2), chown(2), link(2)

7- nice level is process property

9- rlimit should be process-wide and SIGXCPU should be sent if all threads
10  together exceed the limit
11
12- getrusage() must return resource utilization for the process
