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

269Note that C<cf::wait_for_tick> is probably the correct thing to use. This
270variable contains a L<Coro::Signal> that is broadcats after every server
271tick. Calling C<< ->wait >> on it will suspend the caller until after the
272next server tick.
