comparison Python/pythonrun.c @ 42167:29ba6c399090

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Upon exit, flush stdout and stderr (twice: before and after the code that attempts to delete all modules). This makes test_subprocess work again. (I can't quite figure out why stdout/stderr don't get deleted properly, which would flush them anyway, but that's a separate issue.)
