> This involves a change from a single task queue shared amongst all threads to a per-thread task queue and the ability for idle threads to take tasks from other threads' queues (work stealing). 
> As part of this, the task submission API would need to be evolved in some fashion to allow for tasks related to a particular workload to end up in the same task queue
