239These are functions that inhibit the current coroutine one tick. cf::wait_for_tick_begin only 256These are functions that inhibit the current coroutine one tick.

258processing (and consequently, can only wake one thread per tick), while
241per tick), while cf::wait_for_tick wakes up all waiters after tick processing. 259cf::wait_for_tick wakes up all waiters after tick processing.
260
261Note that cf::wait_for_tick will immediately return when the server is not
262ticking, making it suitable for small pauses in threads that need to run
263when the server is paused. If that is not applicable (i.e. you I<really>
264want to wait, use C<$cf::WAIT_FOR_TICK>).
265
266=item $cf::WAIT_FOR_TICK
267
268Note that C<cf::wait_for_tick> is probably the correct thing to use. This
269variable contains a L<Coro::Signal> that is broadcats after every server
270tick. Calling C<< ->wait >> on it will suspend the caller until after the
271next server tick.
