| - setuid/setgid must effect process |
| + test syscalls (getuid) afterwards |
| + 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. |
