No. We do not think that "real multithreading" in Lua (that is, several
preemptive threads sharing a single Lua state) is really a good idea and
so it is not high in our list of priorities. There are several options,
such as coroutines (i.e., non-preemptive multithreading) or threads with
independent Lua states ("Lua processes"). (One thing we are trying to
improve is the ability to yield inside metamethods and for iterators.)
