   I think this is an intended feature, not a bug. 
   
   It's the matter of assumption/definiton of whether the deferred task takes the pool slot or not. I think (but I would love to hear what others think) this is quite a reasonable assumption that deferred task does not take a slot.
   
   Taking into account that the deferred task - by definition takes almost no resources and any external communication is asynchronous and pool feature is designed to limit resources an potentially decrease the loaad/throttle external, mostly synchronous services, I think not taking a pool slot by deferred task is quite reasonable.
   
   Does the task take the slot back when it is back from defferred state @ReadytoRocc ?
