A simple Lua wrapper for pthreads & WIN32 threads.
Each thread gets it's own
lua_State and there is no shared global state.
The parent thread can pass data to a child thread only as parameters when creating
the child thread. The child threads can return data back to the parent thread only
when it return (i.e. ends). The parent needs to call child:join() to get the return
values from a child thread, this call will block until the child thread ends.
The design goals of this module is only provide support for creating new
and running them in a different thread. This module will not provide any
methods of thread-to-thread data passing between running threads (i.e. no locks, no shared state).
Thread to Thread communication methods
The recommend method of passing data between threads is to use ZeroMQ.
