235=item cf::wait_for_tick, cf::wait_for_tick_begin 255=item cf::wait_for_tick, cf::wait_for_tick_begin

259processing (and consequently, can only wake one thread per tick), while
239per tick), while cf::wait_for_tick wakes up all waiters after tick processing. 260cf::wait_for_tick wakes up all waiters after tick processing.
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>).
266
267=item $cf::WAIT_FOR_TICK
268
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.
