170 258
259Note that cf::Wait_for_tick will immediately return when the server is not
260ticking, making it suitable for small pauses in threads that need to run
261when the server is paused. If that is not applicable (i.e. you I<really>
262want to wait, use C<$cf::WAIT_FOR_TICK>).

265
266Note that C<cf::wait_for_tick> is probably the correct thing to use. This
267variable contains a L<Coro::Signal> that is broadcats after every server
268tick. Calling C<< ->wait >> on it will suspend the caller until after the
269next server tick.
