…er `__main__` preload (pythonGH-143717) The forkserver was not passing sys.argv to its main() function, causing sys.argv to be empty during `__main__` module import in child processes. This fixes a non-obvious regression inadvertently introduced by the pythongh-126631 main preloading fix. (cherry picked from commit 298d544) Co-authored-by: Gregory P. Smith <[email protected]>
