262
263Note that cf::wait_for_tick will immediately return when the server is not
264ticking, making it suitable for small pauses in threads that need to run
265when the server is paused. If that is not applicable (i.e. you I<really>
266want to wait, use C<$cf::WAIT_FOR_TICK>).

270Note that C<cf::wait_for_tick> is probably the correct thing to use. This
271variable contains a L<Coro::Signal> that is broadcats after every server
272tick. Calling C<< ->wait >> on it will suspend the caller until after the
273next server tick.
