That pypy3 failure was:

No output has been received in the last 10 minutes, this potentially indicates a stalled build or something wrong with the build itself.

Most likely #1176. I've restarted the build job.

Both CIs now pass.

I wouldn't worry about the Coveralls "failure", it's only recorded the coverage from the restarted job and not the other, older ones.

Anyway, this is just a comment change :)

Bah! Even comments must pass! 😄 Thanks
