260
261Note that cf::wait_for_tick will immediately return when the server is not
262ticking, making it suitable for small pauses in threads that need to run
263when the server is paused. If that is not applicable (i.e. you I<really>
264want to wait, use C<$cf::WAIT_FOR_TICK>).
265

267
268Note that C<cf::wait_for_tick> is probably the correct thing to use. This
269variable contains a L<Coro::Signal> that is broadcats after every server
270tick. Calling C<< ->wait >> on it will suspend the caller until after the
271next server tick.
