The code creates a new .tmp file in the saved_caches directory and then renames it to a non .tmp file name, so there is nothing else with a handle open. The rename is to an existing file though.
Ruslan can you please raise a bug against 0.7.2 for this and include the platform.
Thanks

The "problem" on windows is that it is a bit more worried about rename

So maybe some stream not closed on the file.
