It isn't a "timeout thread", it just a function that is run in the main loop.
It really isn't a matter of right or wrong, it comes down to the fact
that it had to work one way and it so happens that it works like this.
Depending on your intended usage, the way that subsequent timeouts are
called may or may be what you want.

No, the timeout function will block the main loop until it completes;
there will not be multiple threads running your timeout function.
