Yeah, it's definitely specific in some way to docker.

However, it doesn't appear to be 100% reproducible; I just tried a build 
with your reproducer and it completed without problems. (Unless the 
problems are more subtle, and don't prevent a build.) So this one's 
gonna be really fun to track down.
