[issue33725] Python crashes on macOS after fork with no exec

[Barry A. Warsaw]

Barry A. Warsaw <barry at python.org> added the comment:

I have a reliable way to call *something* in the pthread_atfork prepare handler, but I honestly don't know what to call to prevent the crash.

In the Ruby thread, it seemed to say that you could just dlopen /System/Library/Frameworks/Foundation.framework/Foundation but that does not work for me.  Neither does also loading the CoreFoundation and SystemConfiguration frameworks.

If anybody has something that will reliably initialize the runtime, I can post my approach (there are a few subtleties).  Short of that, I think there's nothing that can be done except ensure that exec is called right after fork.
