Unfortunately, practice showed that PyPy is not an answer. It changes
nothing about the poor and coarse thread scheduling. It focuses on the
entirely different aspect of performance, the one which while unpleasant
was not unsurmountable in Python. Checksumming sure is faster, but then
rememebr that Swift offloads Erasure Coding to C already.

We dragged this Python cart 2 years too far already. Don't for a second
imagine that Hummingbird is some kind project prompted by Go being new
and shiny.
