后台监控此类型BUG数量上升很快，逐条查看后，发现都是日志信息都提到了xx.xx.xx:pushcore#Thread-13(9697)。 :pushcore进程是极光推送的所属进程， #Thread-13(9697) 是APP内将robust的初始化另开了线程，在此线程内初始化。 有疑问：

1. 多进程应用，robust的初始化（即PatchExecutor的执行）能不能放在非主进程执行？
2. 非主进程下报错，难道是ClassLoader的进程隔离会大概率影响到热修复类的加载？
3. 初始化robust时，能不能放在单独的Thread里？ eg: Thread { robust init code }.start()
