Threading questions:

Why does the thread proc return a value? (e.g. NULL)
How do you deal with a thread that you don't care when it finishes? So you create the thread, start it, and go on with your life. Must the thread creator destroy the thread at some point, or can the thread destroy itself within its function before it exits?

It follows the pthread design. You can return whatever you like, and retrieve the value with al_join_thread().

You can't do that (yet). The internal API from which the public API evolved never had that ability, because Allegro never needed that itself. It's probably not that hard to add.
