[issue13303] Sporadic importlib failures: FileNotFoundError on os.rename()

[Charles-François Natali]

Charles-François Natali <neologix at free.fr> added the comment:

Then we won't write the bytecode any more.
But it will be consistent.
The solution would be to create a random temporary file (with e.g. mkstemp()): in case of crash, we'll let dangling temporary files, but we'll be able to update the bytecode.
I'm note sure it's worth it (and it won't be easy since we're really restricted in what we're allowed to call).
