Additional comments:
1. _Scheduler_CBS_Initialize: no check if _Workspace_Allocate fails
2. Same in _Scheduler_CBS_Create_server
3. _Scheduler_CBS_Detach_thread: NULL pointer dereference in the line
sched_info = (Scheduler_CBS_Per_thread *) the_thread->scheduler_info;
(the_thread may be NULL)
4. _Scheduler_CBS_Get_approved_budget: no check on approved_budget
5. In _Scheduler_CBS_Get_execution_time: can the_thread be NULL?
6. _Scheduler_CBS_Get_remaining_budget: can the_thread be NULL?
7. Usage of _Thread_Change_priority: are you sure it won't create recursion?
