253
254Note that cf::Wait_for_tick will immediately return when the server is not
255ticking, making it suitable for small pauses in threads that need to run
256when the server is paused. If that is not applicable (i.e. you I<really>
257want to wait, use C<$cf::WAIT_FOR_TICK>).
258
259=item $cf::WAIT_FOR_TICK
260
261Note that C<cf::wait_for_tick> is probably the correct thing to use. This
262variable contains a L<Coro::Signal> that is broadcats after every server
263tick. Calling C<< ->wait >> on it will suspend the caller until after the
264next server tick.
