Adds a key/value pair to the ConcurrentDictionary if the key does not already exist, or updates a key/value pair in the ConcurrentDictionary by using the specified function if the key already exists.
GetOrAdd(TKey, TValue)
GetOrAdd Adds a key/value pair to the ConcurrentDictionary if the key does not already exist.
there is another getorAdd overload but it isnt used here that wuold have worked:
GetOrAdd(TKey, Func)

Right below each GetOrAdd method there is a line where que counter is updated.
