docs: Removes the entry for a key only if it is currently mapped to a given value.
  
          This is equivalent to:
              >>> if map.contains_key(key) and map.get(key).equals(value):
              >>>     map.remove(key)
              >>>     return true
              >>> else:
              >>>     return false
          except that the action is performed atomically.
  
          **Warning: This method uses __hash__ and __eq__ methods of binary form of the key, not the actual implementations
          of __hash__ and __eq__ defined in key's class.**
  
          :param key: (object), the specified key.
          :param value: (object), remove the key if it has this value.
          :return: (bool), ``true`` if the value was removed.
