New issue 2905: "error: release unlocked lock"
https://bitbucket.org/pypy/pypy/issues/2905/error-release-unlocked-lock
hugovk:
The Pillow imaging library is tested against PyPy and PyPy3 (both 5.8) on Travis CI (Linux) and PyPy2 (6.0) on AppVeyor (Windows).
Occasionally the PyPy build on AppVeyor errors. It passes after restarting the build. Here's five. Of a sequence of 19 builds, 5 failed due to this, 13 passed, one was a valid fail. This has been happening since at least July 2018.

Here's our issue on the Pillow tracker: https://github.com/python-pillow/Pillow/issues/3239#issuecomment-433080563
Paul Ganssle just commented there:
> I'm getting the same thing on several dateutil builds using pypy-5.4 on Travis, so I don't think it's related to either PyPy 6.0 or Appveyor. [Example](https://travis-ci.org/dateutil/dateutil/jobs/445799715#L1074)
>
> I never see it on the 3.x series of PyPy, though.
Any ideas what's up?
Thank you!
