This release adds support for passing tables to & from a child thread.
lua-llthreads  is a Low-Level native threads module for Lua. This module
is designed to be a simple wrapper for creating threads from Lua. Each native
thread has it's own lua_State object and shares nothing with it's parent
thread. The module only allows parameters to be
passed to the child thread when it is created and returned from the child
thread to the parent thread only when the parent joins the child thread and
the child thread exits.
For thread-to-thread communication use ZeroMQ  or socket libraries
LuaSocket  or Nixio .
