260Note that cf::Wait_for_tick will immediately return when the server is not
261ticking, making it suitable for small pauses in threads that need to run
262when the server is paused. If that is not applicable (i.e. you I<really>

267Note that C<cf::wait_for_tick> is probably the correct thing to use. This
268variable contains a L<Coro::Signal> that is broadcats after every server
