You have to check for the return value of lua_resume. If it's anything
other than LUA_YIELD, the coroutine is no longer resumable. Anyway you
need to check that value to make sure you don't call lua_resume on it
anymore, so in that check you can also remove the reference you have
in your ThreadTable (and actually if you only resume coroutines from
that table, that's the only thing you need to do).
