在改动debug_console里面的内容时，我寻找原来的设计中能否支持非入侵式地改动，遗憾的是截止至skynet v1.6.0还做不到。 所以我新建了一个仓库skynet_debug_console_enhance来维护这些代码。 因为修改是基于skynet v1.6.0，如果你不是这个版本，覆盖文件后注意检查skynet的接口变化

<CMD:diff_mem OK>sharetable性能参数是从info指令输出的，原来的版本中是没有排序的，在定位哪些配置占用太多内存时，非常杂乱不直观。info指令输出的输出什么内容，是由各个服务自定义解决的，针对sharetable的排序优化，并不能去修改debug_console中的COMMAND.info方法，所以要到sharetable.lua修改里面的skynet.info_func事件处理方法。
以./test/testsharetable.lua为例， :0100000b是我机器此时运行的snlua service_cell sharetable服务的handle值，每次启动都可能不同。你可以从list指令找到对应服务的handle值
