I think he's talking about the transition between Lua 3.2 and 4.0?  In
earlier versions many of the Lua function calls did not take a
lua_State* parameter, so it wasn't as straightforward to make
independent tasks.

The yield() patch I made for 4.0 still has some annoying bugs (that
I'm not planning to fix -- the problems go beyond my level of
understanding of the VM), so that may be a good reason to switch to
5.0w0.  On the other hand, if it's working for you, then no worries.
