Function moduleSetThreadVariablesIfNeeded

src/module.cpp:617–622

This function is used to set the thread local variables (serverTL) for * arbitrary module threads. All incoming module threads share the same set of * thread local variables (modulethreadvar). * * This is needed as some KeyDB functions use thread local variables to do things, * and we don't want to share the thread local variables of existing server threads */
