Hi Quincey,

What you are describing is the role of the scheduler. The scheduler is 
the one that is responsible for pulling user-level threads (ULTs) and 
tasklets from pools and executing them. Think of a scheduler as a 
Pthread. A quick description of how schedulers work can be found at 
https://github.com/pmodels/argobots/wiki/Scheduler. You can also 
checkout an example of how a work stealing scheduler could be 
implemented in `test/basic/sched_user_ws.c` manually.

I am thinking about calling ABT_task_cancel() to get it out of the pool, then just call the task_func (that we gave to ABT_task_create) directly from the place we took it out of the pool.  Will that work?   Is there a better way?
