[issue13645] import machinery vulnerable to timestamp collisions

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Here is a patch adding the source code size to the pyc header.
The number of places where details of the pyc file format are hard coded is surprisingly high...
Unfortunately, I had to modify importlib's public API (path_mtime -> path_stats). I find it unfortunate that importlib's API is vulnerable to pyc format changes.
