Francisco f2a56c9139 simplification of multiqueue design.
- the consumer does multi-staged waiting:
  1. spins first across all queues in a RR fashion
  2. each queue access is done with a try_lock.
  3. if the try_lock fails, it increases the number of spins needed
  2. if no queue had data, the consumer sleeps for 100 usec.
- no differentiation between queues, in terms of notification features

Francisco d947e259c9 stack optimization - optimization of the multiqueue
avoid notifying the consumer side of the multiqueue of a new pushed object, if the
multiqueue already knows that the queue is not empty.

Francisco ef9d1b8c13 stack optimization - reduction of contention in multiqueue class
With the new design, each queue created in the multiqueue object has its own mutex.
Pushing tasks to separate queues will, therefore, not cause contention.
There will be, however, still contention between the popping thread and the pushing threads.
