lua thread newbie

[Jun OKAJIMA <okajima@...>]

Hello.

First of all, I appriciate all guys of Lua team. Interesting language.

I have a bit trouble with lua thread. I made a small sample code of 
just getting some web pages with luathread and luasocket. And it does
not work. Give me any help.

I guess there would be three possible cause.

a, My complie/install of luathread/luasocket is wrong.
   If so, tell me something from ldd output.
b. luasocket does not work under multi threading.
c. just my sample code is wrong.

Note: Two samples ( Parent-child and Producer-consumer from Diego's site)
      works well.

----------------------------
okajima@Debian:~$ lua.thread http.sample.lua
start   2

( this must be like

  ----
   start 2
   start 3
   start 1
   start 4
   http://www.yahoo.co.jp/index.html 1 48712
   .....
   end
  ----
  , but lua terminated just after starting thread 2.
)
----------------------------
okajima@Debian:~$ cat http.sample.lua
function get(str, n)
    local http = require("socket.http")
    local out,len
    print("start", n)
    out = http.request(str)
    len = string.len(out)
    print(str, n, len)
end

thread.newthread(get,{"http://www.yahoo.co.jp/index.html";, 1})
thread.newthread(get,{"http://www.yahoo.com/index.html";, 2})
thread.newthread(get,{"http://www.google.co.jp/index.html";, 3})
thread.newthread(get,{"http://www.google.com/index.html";, 4})

os.execute("sleep 10")
print("end")
