Because Python is not cleaning up after itself. I don't see how a multi-threaded app could work around this issue. The only solution I can think of at the app level is to reset those callbacks once python exits, but a different thread could call an SSL function at any point and cause the crash between the time that _ssl.so is unloaded and the app resets the callbacks.

One solution for Python would be to call CRYPTO_get_id_callback and CRYPTO_get_locking_callback and check that they're NULL before setting them. However, it's also stated in the documentation that id_callback doesn't need to be set for all platforms, so a NULL value could still be safe there. I haven't looked at the callbacks python is setting up, so I can't be sure this solution would work.
