Just so people know, this is how we used to do it. In importlib we write the entire file to a temp file and then to an atomic rename.

Yep, and I suspect that our fix, even if we don't completely identify the root cause, will be to change py_compile.py to do atomic renames. Whether that would be an appropriate fix for 3.2, 3.3 and 2.7 is a different discussion.
