Deep-frozen code objects are cannot be shared (currently) by interpreters, due to how adaptive specialization can modify the bytecodes. We work around this by only using the deep-frozen objects in the main interpreter. This does incur a performance penalty for subinterpreters, which we may be able to resolve later.
