Test:

consistency of queue data handling

• functors of various types can be mixed
• entries are moved in and out of the queue
• no copying whatsoever happens
• each entry gets invoked
• all entries are invoked in order
• enqueuing and dequeuing can be interspersed
• no memory leaks in bound argument data

Test:

torture the CallQueue by massively multithreaded dispatch

• start #NUM_OF_THREADS (e.g. 50) threads in parallel
• each of those has a randomised execution pattern to add new functors and dispatch other thread's functors
