Re: Lua threads share global data?

[John Klimek <jklimek@...>]

Also,  every time I create a thread  (in Delphi using  newThread =
lua_newthread(_luaVM)), the thread seems to remain on the stack even
after my lua_dofile() is finished.

So, after creating five or six threads I have ALL of them on top of
the stack in my main program.  The manual says to use
lua_closethread() after calling lua_dofile() but lua_closethread()
doesn't exist.

Thanks for any help...
