I do not care enough about this to fight about it.

The issue has been open long enough that I do not think it justified the urgency of rushing through a patch just before the release and merging without review, but now that it is in the release of multiple versions, I think we may be stuck with it.

This *is* something that users can work around by not abusing pickle in this way and instead using a proper cross-platform serialization format. I realize that that makes it *more difficult* for some people to do so, but as Gregory points out, these people are doing dangerous stuff that will break in a way that we are not going to be willing or able to fix at some point *anyway*.
