**Steps to replicate the issue** (include links if applicable):
* Run ./pixel.js reference
**What happens?**:
Every so often Pixel hangs after running the `desktop` tests.
**What should have happened instead?**:
Tests are executed to completion
== Developer notes
It seems to run the final test, but for some reason doesn't exit. This is similar to the hanging that was experienced in T318445. I'm not sure why this now seems to occur on x86 machines, though.
