- setuid/setgid must effect process
+ test syscalls (getuid) afterwards
+ test core file content
+ use UID/GID in access(2), chmod(2), chown(2), link(2)
- nice level is process property
- rlimit should be process-wide and SIGXCPU should be sent if all threads
together exceed the limit
- getrusage() must return resource utilization for the process
The following are possible optimizations and in no way required:
- the scheduler should be thread group-aware, i.e., it has to give time to
the thread group not proportional to the number of threads.
