Detailed Description

template<typename ValueType>
struct pfunc::detail::waiting_predicate_pair< prioS, ValueType >

Define the waiting stealing predicate for the priority queue type. We have to ensure that we are stealing a task, which has at least the same priority as the one that we are waiting on. This prevents deadlocks from occuring.
