lua_State Thread Accesses

How is lua_State accessed from different threads. Toward a model of handling it properly.

There are three main types of threads to worry about:

• Command loop: T_{Cmd}
• In general use, this will be blocked 99% of the time waiting on user input
• Event processor: T_{Evp}
• Calling event callback handlers, etc
• any Java thread: T_{Java}
• Short-lived access to push events to the queue

Here are some possible problems:

• Calling a method on T_{Cmd} that triggers an event causing some concurrent execution on T_{Evp}
• Maybe better locking on the queue?
• Any callback on T_{Java} sending an event to the queue causing some concurrent execution with T_{Evp}
• Maybe better locking on the queue?
