-This function specifies the condition variable associated to a worker per context
-When there is no available task for a worker, StarPU blocks this worker on a
-condition variable. This function specifies which condition variable (and the
-associated mutex) should be used to block (and to wake up) a worker. Note that
-multiple workers may use the same condition variable. For instance, in the case
-of a scheduling strategy with a single task queue, the same condition variable
-would be used to block and wake up all workers.
-The initialization method of a scheduling strategy (@code{init_sched}) must
-call this function once per worker.

 Each scheduling policy uses some specific data (queues, variables, additional condition variables).
 It is memorize through a local structure. This function assigns it to a scheduling context.
