New submission from Bar Harel:

After asking a question regarding performance in StackOverflow, I received an answer which seemed like a design problem in object allocation.
This is the question: http://stackoverflow.com/q/36548518/1658617
Seems like it ignores the garbage allocation settings (as timeit is supposed to disable it as far as I know) and I might not be proficient in low-level programming but there should be a way to implement it that doesn't cause endless allocations.
