Has it since been fixed?

  Probably not. CPickle is famously shunned by anyone who has to do serious, performance-critical serialization/deserialization.

    I was curious, and an issue that fits the description was fixed in Py 3.7.x here: https://bugs.python.org/issue34572 https://bugs.python.org/issue34572 but other threading bugs remain: https://bugs.python.org/issue38884 https://bugs.python.org/issue38884

    What’s the most performance critical alternative? Pickle is tied to the VM, so it’s not a generally good persistence option in a prod setup, but it can mighty convenient.

    What do people use instead?

      JSON, protocol buffers, thrift, etc. Saving python-native objects such as functions, class instances etc is usually not the right thing to do in production code.
