You cannot access a single Lua state simultaneously from several
threads. You have to implement a locking mechanism, as Ong hean kuan
suggested. That's what LuaThread does, and you are probably already
doing it since otherwise you generally get problems quickly.

In that situation (a single locked Lua state), the use of LuaJIT is
transparent, it's a drop-in replacement for the default Lua
implementation.
