Previous: Task Creation and Deletion:
- Donation of inactive tasks allows passing of creation right.
- Deleting an inactive task does not affect version number.
- Deleting a task implicitly deletes all tasks in its clan or
subclans.
- Only a task's chief can execute a task_new syscall for
it
- Exception (MIPS): Anyone can call task_new for a task
which has never been active.
- Means of allocating task creation rights at system startup.
