原型： static Instruction symbexec (const Proto *pt, int lastpc, int reg);
symbexec 是安装vm的执行流程来模拟一段opcode的执行， 执行到lastpc, 同时返回修改reg的那条指令。
有2个用途
1. loadstring检查代码是否被篡改，是否合法
2. 用于lua_getinfo的时候 看一个first class的function是global,local,upval 还是其他东西。
总之设计还是很巧妙的。
一直对coroutine的运作原理不是很明白， 这几天琢磨了下终于搞明白了：
root@yfnix:~/lua-5.1.3/src# cat t.lua
a= coroutine.create(function ()
b= coroutine.create(function ()
coroutine.yield(1)
end)
coroutine.resume(b)
end)
coroutine.resume(a,1)

R12B发布以后 号称ASN.1解码速度快了好多。前天仔细看了文档，感觉用在自有的系统去不错。ASN.1的结构还是很紧凑的，BER,PER,BER_BIN,PER_BIN都支持。特别是支持选择性decode,这个feature非常赶兴趣。用在自己的项目里面就省去了很多协议编解码的繁琐和易错,毕竟asn compiler也做了几万行 我相信他的性能。

shutdown(Socket, How) -> ok | {error, Reason}
Types:
Socket = socket()
How = read | write | read_write
Reason = posix()
Immediately close a socket in one or two directions.
How == write means closing the socket fo ...
