Description
你好，openresty，麻烦咨询个问题：在lua_code_cache开启的情况下，我在某个worker中初始化的模块变量（仅初始化一次），能在另外的worker中获得这个模块变量的初始值吗？还望你的及时回答。源码中，其中有一个全局注册表的概念，他的机制是怎么样的？

Research direction
Start by tracing the lua_code_cache behavior and the global registry mechanism in the lua-nginx-module source; the issue does not name specific files or tests. Determine whether module variables initialized in one worker are visible to another, then document the worker-scope behavior and registry mechanism as the completion criteria.
