SublimeREPL 输出换行很怪异

F5 运行多次，每次换行还不一样

代码

class Singleton(object):

    def __init__(self):
        import time
        time.sleep(1)

    @classmethod
    def instance(cls, *args, **kwargs):
        if not hasattr(Singleton, "_instance"):
            Singleton._instance = Singleton(*args, **kwargs)
        return Singleton._instance

import threading

def task(arg):
    obj = Singleton.instance()
    print(obj)

for i in range(10):
    t = threading.Thread(target=task,args=[i,])
    t.start()

配置如下

    {
        "keys":["f5"],
        "caption":"SublimeREPL: save & Python - RUN current file",
        "command":"chain",
        "args":
        {
        "commands":[
            ["save"],
            [ "run_existing_window_command",{"id": "repl_python_run","file": "config/Python/Main.sublime-menu"}]
               ]
        }
    },
