175 254
255Note that cf::Wait_for_tick will immediately return when the server is not
256ticking, making it suitable for small pauses in threads that need to run
257when the server is paused. If that is not applicable (i.e. you I<really>
258want to wait, use C<$cf::WAIT_FOR_TICK>).

262Note that C<cf::wait_for_tick> is probably the correct thing to use. This
263variable contains a L<Coro::Signal> that is broadcats after every server
264tick. Calling C<< ->wait >> on it will suspend the caller until after the
265next server tick.
