Also Lua threads don't necessarily have the "routine" part of
coroutines. coroutine.create takes a function to be run, but from C
you can create a thread and use it without ever calling a function in
it. It's sometimes useful for example to store temporary data when
binding C APIs involving callbacks (you create a clean thread, pass
it's lua_State* as the API void*, have the callback push values, and
xmove them afterwards).
