Coroutine environment

["Alexander Gladysh" <agladysh@...>]

Hi, all!

The old Lua 5.0 manual in Threads section says following:

 http://www.lua.org/manual/5.0/manual.html#3.20

 Each thread has an independent global environment table. When you create a
 thread, this table is the same as that of the given state, but you
can change each
 one independently.

I can't find anything confirming this neither in the new 5.1 manual,
nor in the PiL I book. Is it correct that Lua makes copy of global
environment for each coroutine thread, or coroutines use exactly the
same environment they were created in?

Thanks in advance,
Alexander.
