Thanks a lot, Brandt for doing the benchmarking!
I think that unpack_sequence is **very** affected by code locality. I was debugging it recently with Linux perf (https://perf.wiki.kernel.org/index.php/Main_Page) and it shows that is extremely affected by L1-L2 cache performance. I still need to understand why, but yeah, I am fine ignoring it.
>All things considered, I believe we should fix this... I personally view memory leaks as second only to crashes and incorrect behavior in terms of severity.
Yeah, I very much agree with you. Could you convert your patch into a PR?
