HSCondition: Fixed terrible bug which it inherited from its default python Condition implementation, related to the notify method not being treadsafe. Although I was aware of it, I missed the first check which tests for the size - the result could be incorrect if the whole method wasn't locked.

Testing runs stable now, allowing to move on \!
