The thing is, in two years the project was able to deliver only a very small, say 1.2x, speedup, with a noticeable increase of memory (sometimes 3x). Against Python 2.6. I wouldn't be surprised if Python 2.7 is actually faster on some tests. Is it really worth keeping working on it and merging?

Part of the reason Python 2.7 is faster on some benchmarks is because of the patches the unladen swallow team pushed upstream into core.
