Yes, this is required for the THREAD_CPU_BUDGET_ALGORITHM_RESET_TIMESLICE 
algorithm.  An alternative is THREAD_CPU_BUDGET_ALGORITHM_EXHAUST_TIMESLICE.

As Joel already mentioned it might be useful to add an option to the Classic 
API to use THREAD_CPU_BUDGET_ALGORITHM_EXHAUST_TIMESLICE instead of 
THREAD_CPU_BUDGET_ALGORITHM_RESET_TIMESLICE.
