it might be probably better to handle this corner case and make it hard error
otherwise we're not aware about it.

It's caused by something in between tmpfs (those 2 workers are building in
RAM), Docker container and host kernel. I've moved the /tmp from Docker
container to the tmpfs on the host, but it's still hapenning. 

Anyway, restarting the Docker containers always fixes this issue so should be
"fixed" for now. Thank you for reporting it!
